Step-by-step explanation: 1. What this is asking is to make the fraction a bit easier to understand. So all we do is divide the numerator by the denominator. You can use this method for any other math problems like this also.

2. All this chart is doing is multiply the input or output by 9. If you look you can see the hours is multiplied by nine. I hope this helped.

1. Simplify the expression. Show your work.

$$\sqrt{\frac{4 x^{2}}{3 y}}=\frac{2x }{\sqrt{3y} }$

Solution:

Given expression:

$$\sqrt{\frac{4 x^{2}}{3 y}}$

To simplify the given expression:

4 can be written as 2 × 2 = 2²

x can be written as x × x = x²

$$\sqrt{\frac{4 x^{2}}{3 y}}=\sqrt{\frac{2^2 x^{2}}{3 y}}$

$$=\sqrt{\frac{(2 x)^{2}}{3 y}}$

Using radical rule: $\sqrt{\frac{a^m}{b^m} } =\frac{ \sqrt{a^m} }{ \sqrt{b^n} }$

$$=\frac{\sqrt{(2x)^2} }{\sqrt{3y} }$

In numerator square and square root get cancelled.

$$=\frac{2x }{\sqrt{3y} }$

$$\sqrt{\frac{4 x^{2}}{3 y}}=\frac{2x }{\sqrt{3y} }$

Hence the expression is simplified.
