First, let's work with the denominator alone:
4⁻⁴ = 1 / 4⁴ = 1/256 .
The original problem is the reciprocal of that = 256.
9x^5-4x^2+7x-3 is the simplified version of your answer.
Answer:
9. Supplementary (angles adds to 180)
10. complementary (angles add to 90)
11.
6x+4=10x
/6x
4=4x
x=1
12.
8+7
90/15
x=6
