Question

HELP ME PLEASE!!!!

Answer 1

`64=4\cdot4\cdot4=4^3\\\\\left((1)/(4)\right)^(c-2)=64\\\\\left((1)/(4)\right)^(c-2)=4^3\\\\\left((1)/(4)\right)^(c-2)=\left((1)/(4)\right)^(-3)\iff c-2=-3\ \ \ |+2\\\\\boxed{c=-1}\\\\\text{check}\\\\L_s=\left((1)/(4)\right)^(-1-2)=\left((1)/(4)\right)^(-3)=4^3=64=R_s\\\\\text{correct :)}`

`\text{Used:}\\\\a^(-n)=\left((1)/(a)\right)^n`
