Describe how to transform the quantity of the third root of x to the fourth power, to the fifth power into an expression with a
Novosadov [1.4K]

Answer:

x^{\frac{20}{3} }

Step-by-step explanation:

To write: third root of x to the fourth power, to the fifth power into an expression with a rational exponent

Solution:

Exponent refers to the number of times a number is multiplied to itself.

Exponent is sometimes also known as power.

Third roots of x=x^{\frac{1}{3} }

Third root of x to the fourth power(x^{\frac{1}{3} })^4 =x^{\frac{4}{3} }

Third root of x to the fourth power, to the fifth power=(x^{\frac{4}{3} })^5= x^{\frac{20}{3} }

natima [27]

Use the substitution method

w(x)=9x+8

w(5)=9(5)+8

Do the parenthesis first then add because of using PEMDAS

P= Parentheses

E= Exponents

M= Multiplication

D= Division

A= Addition

S= Subtraction

45+8

=53

Answer: w(5)=53

Find the value of x.
svetoff [14.1K]

Answer:

x = 28

Step-by-step explanation:

The ratios of corresponding sides are equal, that is

\frac{12}{8} = \frac{x-7}{14} ( cross- multiply )

8(x - 7) = 168 ( divide both sides by 8 )

x - 7 = 21 ( add 7 to both sides )

x = 28

What is the value of v?
frosja888 [35]

Answer: v = 32 degrees

Step-by-step explanation:

The polygon theorem states that for any polygon with n sides, the sum of the interior angles is (n - 2) × 180

The given polygon has 6 sides. Therefore, n = 6

The sum of the angles in the polygon is

(6 - 2) × 180 = 3 × 180 = 540 degrees

Therefore,

119 + 134 + 108 + v + 47 + 2v + 2v - 28

Collecting like terms, it becomes

119 + 134 + 108 + 47 - 28 + v + 2v + 2v = 540

380 + 5v = 540

5v = 540 - 380

5v = 160

v = 160/5

v = 32 degrees
