6^(x+3)=40
6^(x+3)=2³•5
x+3=log_6(2³•5)
x+3=log_6(2³)+log_6(5)
x+3=3[log_6(2)]+log_6(5)
x=-3+3[log_6(2)]+log_6(5) ❤

Tebrik ederim.

6x + 18 = 40
6x = 40 - 18
6x = 22
x = log 22 / log 6
x = 1.72514
6^1.72514 = 22

(x+3)log6=log40
x=log40/log6-3=(2log2+log10)/(log2+log3)-3
x≈(2×0.301+1)/(0.301+0.477)-3≈-366/389≈-0.941
Deviation is about 0.0003
6^(-0.941+3)≈40.01
