Answer:

a) 4

b)
(1)/(2) √(y^5)

Explanation:

PART A

Simplify the expression by solving out the square roots.


(√(16) √(p) )/(√(p)) =
(4 √(p) )/(√(p))

You can cancel out the
√(p) on the top and bottom.

So, a should be 4.

PART B

Solve out the square root. The square root is pretty much the 1/2 power, so you can divide the exponents by half.


\frac{\sqrt{y^(10)} }{\sqrt{4y^(5)} } =
\frac{y^(5)}{2y^{(5)/(2)} }

You can subtract exponents to divide them. So the y variable becomes
y^(5 - 5/2), or
y^(5/2).

Then, the overall expression is
(1)/(2) y^{(5)/(2) }, or you can turn that into
(1)/(2) √(y^5).
