The goal of any equation is to get the VARIABLE by itself on one side of the equation.
(0.4)² = (0.4).(0.4) = 0.16
His error is, instead of raising (0.4) to exponent 2, he multiplied (0.4) by 2 , obviously which is wrong
I think the answer is 5, if you divide 7.5 by 1.45 you get 5.2 or 5.17 so approximately 5.
