[ooABoo]

but its too obvious from the fact that the left x opertion has to result in sqrroot of 16 to give 4 so x+2 has to be 1/2 so x = -1.5

[KlementineAshipala-hsxy]

If you substitute x the answer is not 4

[hangthuy]

4^2(x+2)=4^1
2x+4=1
2x=1-4=-3
X=-3/2

[nonenone]

And ehen would this have a practical purpose?
