Okay, so how do i know that, how do i solve this algebraically? well, notice i have an exponent of x.
00:06
Okay, so what's the inverse of the exponential function? the logarithm of function.
00:11
So to move this exponent down, what i could do is i could take heat.
00:15
I can use just my natural log, which is log -based e, or i could use just log, which is assumed as log -based head.
00:22
I could use either because these are on my calculator.
00:24
I'm going to use my natural law.
00:26
It doesn't matter which one i use, but i'm just going to choose my natural log.
00:29
So ln of 2 equals i have this exponent up top.
00:34
So this comes down, multiplies at bottom by rules of logarithms...
