Answer:

Step-by-step explanation:

What are the Factors of 20

Factors of 20 =1, 2, 4, 5, 10, 20

Distinct Factors of 20 = 1, 2, 4, 5, 10, 20,

Note: Factors of 20 and Distinct factors are the same.

Factors of -20 = -1, -2, -4, -5, -10, -20,

What are the Factors of 23

Factors of 23 =1, 23

Distinct Factors of 23 = 1, 2, 4, 5, 10, 20, 1, 23,

Note: Factors of 23 and Distinct factors are the same.

Factors of -23 = -1, -2, -4, -5, -10, -20, -1, -23,

Negative factors are just factors with negative sign.

How to calculate factors of 20 and 23

The factors are numbers that can divide 23 without remainder.

Every number is divisible by itself and 1.

Factors of 20

20/1 = 20         gives remainder 0 and so are divisible by 1

20/2 = 10         gives remainder 0 and so are divisible by 2

20/4 = 5         gives remainder 0 and so are divisible by 4

20/5 = 4         gives remainder 0 and so are divisible by 5

20/10 = 2         gives remainder 0 and so are divisible by 10

20/20 = 1         gives remainder 0 and so are divisible by 20

Factors of 23

23/1 = 23         gives remainder 0 and so are divisible by 1

23/23 = 1         gives remainder 0 and so are divisible by 23

20,23

 

The real common factors of 20,23 is 1

LCM of 20 and 23

Multiples of 20= 20, 40, 60, 80, 100, 120, 140, 160, 180, 200, 220, 240, 260, 280, 300, 320, 340, 360, 380, 400,

Multiples of 23= 23, 46, 69, 92, 115, 138, 161, 184, 207, 230, 253, 276, 299, 322, 345, 368, 391, 414, 437,

Least common multiple (LCM) of 20 and 23= 460

HCF of 20 and 23

Highest common factor (HCF) is calculated using real common factors above

HCF of 20 and 23 = 1

GCF of 20 and 23

Greatest common factor (GCF) is the same as Highest common factor (HCF)

GCF of 20 and 23 = 1

LCD of 20 and 23

lowest common Denominator (LCD) is the same as Least common multiple (LCM)

lowest common Denominator (LCD) of 20 and 23= 460

We get factors of 20,23 numbers by finding numbers that can divide 20,23 without remainder or alternatively numbers that can multiply together to equal the target number being converted.

In considering numbers than can divide 20,23 without remainders. So we start with 1, then check 2,3,4,5,6,7,8,9, etc and 20,23

Getting factors is done by dividing 20,23 with numbers lower to it in value to find the one that will not leave remainder. Numbers that divide without remainders are the factors.

Factors are whole numbers or integers that are multiplied together to produce a given number. The integers or whole numbers multiplied are factors of the given number. If x multiplied by y = z then x and y are factors of z.

if for instance you want to find the factors of 20. You will have to find combination of numbers that when it is multiplied together will give 20. Example here is 5 and 4 because when you multiplied them, it will give you 20. so they are factors of the given number 20. Also 1 and 20, 2 and 10 are factors of 20 because 1 x 20 = 20 and 2 x 10 = 20. The factors of the given interger number 20 are 1, 2, 4, 5, 10, 20

To calculate factors using this tool, you will enter positive integers, because the calculator will only allow positive values, to calculate factors of a number. if you need to calculate negative numbers, you enter the positive value, get the factors and duplicate the answer yourself with all the give positive factors as negatives like as -5 and -6 as factors of number 30. On the other hand this calculator will give you both negative factors and positive integers for numbers. For instance, -2 , -3,-4 etc.

factors is like division in maths, because it gives all numbers that divide evenly into a number with no remainder. example is number 8. it is is evenly divisible by 2 and 4, which means that both 2 and 4 are factors of number 10.

Can someone solve this? and tell me how?
maksim [4K]

Answer:

1/3

Step-by-step explanation:

When working with balanced expressions (stuff on both sides of the equal sign), "what you do to one side, you do to the other", which keeps it balanced.

The first thing we notice is the exponent 1/4, which is one both sides, so we can get rid of it on both sides by using the <u>reverse operation</u>.

The reverse of exponents is <u>square root</u>.

(4x + 10)^{\frac{1}{4}} = (9 + 7x)^{\frac{1}{4}}\\\sqrt[\frac{1}{4}]{(4x + 10)^{\frac{1}{4}}} = \sqrt[\frac{1}{4}]{(9 + 7x)^{\frac{1}{4}}}\\\\4x + 10 = 9 + 7x

Isolate x to solve. Separate the variables and non-variables.

4x + 10 = 9 + 7x

4x - 4x + 10 = 9 + 7x - 4x          Subtract 4x from both sides

10 = 9 + 3x                

10 - 9 = 9 - 9 + 3x            Subtract 9 from both sides

1 = 3x            Divide both sides by 3 to isolate x

x = 1/3           Answer
