Answer 1

I though i'd reopen a new one. Was afk for a long time

Answer 2

so parentheses isn't there ? right ?

Answer 3

I subtract 2 from both sides

log10 (2x^2) + 2 -2 = 6-2

log10 (2x^2)=4

I then used a = logb (b^a)

so... 4= log10 (10^4)

log10 (2x^2) = log10 (10^4)


then all this other stuff/ not sure I want to type it all out lol
