<h3>
Answer: 9</h3>
========================================================
Work Shown:
Apply the pythagorean theorem
a^2 + b^2 = c^2
12^2 + b^2 = 15^2
144 + b^2 = 225
b^2 = 225-144
b^2 = 81
b = sqrt(81)
b = 9
1 / 9^4 and 1 / 6^3
This is because in order to make a negative exponent into a postive exponent, you need to make it into a fraction, 1 as the top number, and the negative exponent as a postive one.
For example, 6^-3 becomes 1 / 6^3.
I hope I helped.
