Question

x^(3/4)=27 How do I solve this equation?

Answer 1

x=81

Raise each side of the equation to the 4/3 power to eliminate the fractional exponent on the left-hand side.

Then solve for X

Answer 2

\(\bf \large x^{\frac{3}{4}}=27 \implies \sqrt[4]{x^3} = 27\\
\textit{raise both sides by 4}\\
\left(\sqrt[4]{x^3}\right)^4 = (27)^4 \implies x^3 = (27)^4\)
