## anonymous one year ago Solve log 2x^2 + 2 = 6. Round to the nearest thousandth if necessary.

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

2. Nnesha

so parentheses isn't there ? right ?

3. Nnesha

you can tag me 'n the last post :=)

4. anonymous

nope no parenthesis look just like this $2x^2 + 2 =6$

5. Nnesha

alright so you work is correct!

6. Nnesha

ur*

$$\color{blue}{\text{Originally Posted by}}$$ @lostinprague 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 $$\color{blue}{\text{End of Quote}}$$
