NEED RN, WORTH 50!<br> What is the value of x?
xxTIMURxx [149]

Answer:

x = 5

Step-by-step explanation:

<u>Step 1:  Make an equation</u>

<u />\frac{32}{40} = \frac{4}{x}

<u>Step 2:  Cross multiply</u>

<u />\frac{32}{40} = \frac{4}{x}

32 * x = 4 * 40

32x = 160

<u>Step 3:  Divide both sides by 32</u>

<u />32x / 32 = 160 / 32

x = 5

Answer:  x = 5

Simplify the given expression, using only positive exponents. Then complete the statements that follow. [ (x2y3)−1 (x−2y2z)2 ] 2
Firlakuza [10]

Answer: y²z⁴ / x¹²

  • The exponent of x is 12

  • The exponent of y is 2

  • The exponent of z is 4

Explanation:

1) Given expression to simplify:

((x^2y^3)^{-1}(x^{-2}y^2z)^2)^2

2) Property: power of power:

(x^{-4}y^{-6})(x^{-8}y^8z^4)

3) Property: product of powers with the same base

x^{(-2-8)}y^{(-6+8)}z^4

4) Add the exponents

x^{-12}y^2z^4

5) Pass the negative power to the denominator:

\frac{y^2z^4}{x^{12}}

The exponent on x is  12. The exponent on y is 2. The exponent on z is 4.
