Question

What Is The Square Root Of x^9.?

Answer 1

I believe it would be x^3... it's been a while since I've done that stuff.

Answer 2

the square root of x*x is x
the square root of x*x * x*x is x*x

you take out "pairs of x"

x^9 has 9 x's
how many pairs can you take out

Answer 3

in other words write x^9 as x* x^8
\[ \sqrt{ x^8 \cdot x} \]
now you have 4 pairs of x's you can take out of the root sign, leaving one x inside
