Question

X^3/2=27, find value of x

Answer 1

My guess is
\[x^{3/2}=27\]?

Answer 2

yes

Answer 3

x=27^2/3
x=((27)^1/3)^2=(3)^2=9

Answer 4

27=3^3
27^1/3=(3^3)^1/3=3

Answer 5

Square both sides, you'll get
\[x^3=27^2\]
\[x^3=729\]
Then the cubed of 9 is 729, so rewrite it as
\[x^3=9^3\]
Then 3 cancels out from the exponents
