Answer:
a) 4
b)
Step-by-step explanation:
<u>PART A</u>
Simplify the expression by solving out the square roots.
=
You can cancel out the on the top and bottom.
So, a should be 4.
<u>PART B</u>
Solve out the square root. The square root is pretty much the 1/2 power, so you can divide the exponents by half.
=
You can subtract exponents to divide them. So the y variable becomes , or
.
Then, the overall expression is , or you can turn that into
.
