How do I square $\log_2(3)$. Does it become $2\log_2(3)$ ?
No. $(\log_2(3))^2$ can't be simplified.
However, $\log_2(3^2)=2\log_2(3)$.

Find the number b such that the average value of f(x)=2+6x-3x^2 on the intervak [0, b] is equal to 3.
so I did the integal from 0 to b of 2+6x-3x^2 which is 2x+3x^2-x^3
now what? Do i set it equal to 3 and find out what b is?
