Remember this rule?
x^(ab) = x^a^b
You have:
9^(3/2)
Which can be rewritten as:
9^(1/2 * 3)
Using the exponent rule above:
9^(1/2)^3
The first part is the same as sqrt(9):
[√9] ^ 3
Simplify:
3^3
Answer:
27

do you mean 9^3/2 = (9^3)/2 = 729/2=364.5
or 9^3/2 = (9)^3/2 = [(9)^1/2]^3 = 3^3 = 27

Take the square root of 9.
sqrt(9)=3.
Take that, and cube it.
3^3 = 27.

depends, is it (9^3)/2 or is it 9^(3/2)?
for the first, it is 9*9*9/2
for the second, it is (9^(1/2))^3=3^3=3*3*3

It's the square root of 9 cubed
Square root of 9x9x9, which is 729
Square root of 729 is 27
