Question 811931: I have a problem trying to solve this logarithm. log base 3 (x^2+1)=4
log3(x^2+1)=4. According to the log rules of logb(+/-) it can be rearranged unless it's multiplication and division, but this has something in the parentheses so how would I go about solving this?

= 4
The exponent equiv of logs
(x^2+1) =
x^2 + 1 = 81
x^2 = 81 - 1
x^2 = 80
x =
x =
x =
