Complete the steps to simplify (y^4/3•y^2/3)^-1/2. Apply the product of powers property to the expression inside the parentheses
MrRissso [65]

Option A

\left(y^{\frac{4}{3}} \cdot y^{\frac{2}{3}}\right)^{\frac{-1}{2}} = \left(y^{2}\right)^{\frac{-1}{2}}

<em><u>Solution:</u></em>

<em><u>Given expression is:</u></em>

\left(y^{\frac{4}{3}} \cdot y^{\frac{2}{3}}\right)^{\frac{-1}{2}}

<em><u>Product of powers property:</u></em>

The product of powers property tells us that when you multiply powers with the same base you just have to add the exponents

Which is represented as,

a^m.a^n = a^{m+n}

<em><u>Therefore, the given expression becomes,</u></em>

\left(y^{\frac{4}{3}+\frac{2}{3}}\right)^{\frac{-1}{2}}

Now add the exponents, we get

\left(y^{\frac{4+2}{3}}\right)^{\frac{-1}{2}}

Simplify the above expression

\left(y^{\frac{6}{3}}\right)^{\frac{-1}{2}}

Simplify the exponent of y, we get

\left(y^{2}\right)^{\frac{-1}{2}}

Thus Option A is correct

which of the following correctly gives the center and radius of the circle defined by the equation (z-7)^2 = 10?
ANEK [815]

Answer:

Center (7,2); Radius - Square Root of 10

Step-by-step explanation:

Equation for a Cricle:

(x−h)^2 + (y−k)^2 = r^2

Where:

h = x-coordinate of the center of the circle

k = y-coordinate of the center of the circle

r = radius of the circle

For this problem, your h = 7, k = 2, and r = square root of 10
