help me solve this?

Question

Approximate the following logarithms using the properties of logarithms given

log base b (216)=

log base b (100)=

log base b (125b^4)=

I will be forever gratful

Answer 1

It says approximate, so it looks like they don't want a strictly numerical answer.

b to the power of what equals 216?

They might just want you to write b ^ x = 216.

or b ^ x = 100

In order to actually solve the problem you will need a numerical value for b. Are you sure "b" isn't a 6?

Answer 2

I will be forever gratful if you tell us what "b" is.
