the answer is $\frac{29}{4}$ $29/4$ or $7^{\frac{1}{4}}$ $7^(1/4)$

Explanation:

first you have to get rid of the $4$ $4$ so you divide it to both sides(division is the counter of multiplication) and so now you have to counter the $\sqrt{}$ $sqrt$ so you have to squared to counter it. so you'll get ${(\frac{1}{2})}^{2}$ $(1/2)^2$ and so you have to solve that and you get your answer
