Question

if x=64 and y=20 then what is the value of:
x to the power of one half + y to the power of one half

Answer 1

I will assume we are using positive roots....

if x=64 and y=20 then:

x^(1/2)+y^(1/2)

√x+√y

√64+√20

√20+8

2√5+8

2√5+2*4

2(4+√5)

Answer 2

To the power of one half is the square root.
