Take logs of both sides
0.32
log(2.8)log(5)\frac{\log(2.8)}{\log(5)}log(5)log(2.8)
Yes, gives same result
Raise 6 to both sides: x=60.2x = 6^{0.2}x=60.2
Can't split exponentials: 101+102≠10310^1+10^2≠10^3101+102=103
Combine to get log(x3)=4\log(x^3) = 4log(x3)=4
Logarithms of negatives don't exist
(x+3)log(2)=log(7.2)(x+3)\log(2) = \log(7.2)(x+3)log(2)=log(7.2)
