Question #382f7

1 Answer

Jan 22, 2017

$x = 9998$ $x=9998$

Explanation:

Isolate log(x+2) by dividing both sides by $\frac{1}{2}$ $1/2$

$\Rightarrow log (x + 2) = 4$ $rArrlog(x+2)=4$

$color(orange)"Reminder " color(red)(bar(ul(|color(white)(2/2)color(black)(log_b x=nhArrx=b^n)color(white)(2/2)|)))$

$color(blue)"Note"$

$log(x+2)" represents" log_(10)(x+2)$

$log_(10)(x+2)=4rArrx+2=10^4=10000$

$rArrx=10000-2=9998$
