Question

can anyone teach me how to simplify numbers with fractions as exponents??? please! :)

Answer 1

you got an example?

Answer 2

i just want to know the basics so I can apply it to the question (81x^2/y)^3/4

Answer 3

\[\huge b^{\frac{n}{m}}=\sqrt[m]{b^n}\]

Answer 4

\[81^{\frac{3}{4}}=\sqrt[4]{81^3}=3^3=27\]

Answer 5

so is that the same for every question?

Answer 6

same idea
if you have variables you just multipiy the exponents, so
\[\huge (x^2)^{\frac{3}{4}}=x^{\frac{3}{2}}\]

Answer 7

okay! thanks so much!! (:
