(xm.x2)3(k3)5 = x21k15 Find the Value of M

Answer:

m=5

Step-by-step explanation:

Given:

([(x^m) (x^2)]^3) ([k^3)^5]= (x^21)(k^15)

we can simplify this equation by understanding what operation that was applied to the x and k variables

we can pridect that they were using the multiplication method of exponents by distribution as follows:

if we look at x^21 at the right side of the equation then we shold have the same nuber of x multiples such that:

21= (3)(7) but if we look at the right hand side we have some missing information but we can still use the multiplication of the exponent and subtract it from the right hand side as follows:

first distribute 3 for both x's in the left hand side:

(x^m)^3= x^(3)(m)

and

(x^2)^3= x^(2)(3)

⇒will give us:

(x^3m)(x^6)=(x^21)

let us now check by ignoring the x's and use the exponents in the form of an equation:

(3m)+(6)=21

move 6 to the right side

3m = 21-6

3m=15

m= 15/3

m=5

so, by substituting 5 with m at the original equation we will get:

(x^5(3)) (x^6) = x^21

(x^15)(x^6)=x^21

that applies the same rule to the variable k

k^3(5)=k^15

asambeis [7]

Answer:

The 1st selection is appropriate.

_____

2nd: the rotation would need to be 90° CCW

3rd, 4th: rotation or double reflection will give the original orientation. This figure is reflected an odd number of times, so has its orientation reversed.

You have $550 in a savings account that earns 3% simple interest each yaer. How much will be in your account in 10 years?
bija089 [108]
Looking at the given question, we can find several important information's and based on thm we can easily calculate the amount after 10 years.
Principal amount = $550
Rate of interest per year = 3%
Number of years the amount is to be kept = 10 years
Now we get put these information's in the formula of finding amount of money kepy in simple interest.
Amount = P(1 + rt)
Where
p = principal amount
r = rate of interest
t = Time
Then
Amount = 550[1 + (3/100) * 10)]
             = 550 [1 + 3/10]
             = 550 * (13/10)
             =  55 * 13
             = 715 dollars
So the total amount in my account will be $715
