Question

find x, x^(-3/4)=1/8​

Answer 1

Answer:

x = 16

Step-by-step explanation:

 $x^{\frac{-3}{4} } = \frac{1}{8}$

$x^{\frac{-3}{4} } = \frac{1}{2^{3} }$

$x^{\frac{-3}{4} } =2^{-3}$

$x^{\frac{-3}{4} * \frac{4}{3} } =2^{-3*\frac{4}{3}}$    ( multiply both side's exponents by 4/3)

$x^{-1} = 2^{-4}$

$x = 2^{4} = 2 * 2 * 2 * 2 = 16$
