The correct answer is: 3Step-by-step explanation:
Instead of sharing the conventional tedious, method, let me share with you the simple trick here to solve these types of questions without using the calculator:
Given
![log_464](https://img.qammunity.org/2019/formulas/mathematics/middle-school/u5pye6rns3rjywurlsreeqthgasv1zis1m.png)
It is essentially saying that WHAT power of 4(which is the base of log) gives us the value 64. You need to find the answer to that "WHAT."
Well
![4^1 = 4 \\ 4^2 = 16 \\ 4^3 = 64](https://img.qammunity.org/2019/formulas/mathematics/middle-school/3p1y5bm4j6cnt0erded9z54m6qlsopub78.png)
Hence the answer is "3".
