Answer:

the answer is #29/4# or #7^(1/4)#

Explanation:

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