Question

the square root of x^7

Answer 1

Remember,
\[\sqrt{a}=a^{1/2}\]

Answer 2

\[x^7 = x*x*x*x*x*x*x\]

Answer 3

Similarly,

\[\sqrt{a^5}=a^{5/2}\]


Now you decide

\[\sqrt{a^7}=\]

Answer 4

x^(7/2)

And remember, this is defined only for x >= 0 because x^7 is negative for x < 0

Answer 5

or\[\sqrt{x*x*x*x*x*x*x} = x^3 \sqrt{x}\]
