Step-by-step explanation:
Hi there,
To solve this, we want to isolate x either using logs or exponent rules. For this, I chose exponent rules.
First, divide both sides of the equation by (1/3)² :

The right-hand side is reduced to 1. The left-hand side contains values that have the same base, so we can use this exponent rule:
Apply this:
Now, we are left with:
Conceptually, you just have to think: <em>what exponent can make a base equal to 1? </em>
This is based on the following exponent rule:

So, all we have to do is set (x-4) = 0!

Thus, the value of x is 4.

Hello! First insert 6 where the h is located. So we have an equation that looks like the following.
Although you could leave the equation in its original form, I am going to switch it around.
Move the 6 to the other side and do the math
Factor and after factoring your T will be as followst =

= -0.1900
t =

= 1.315
