Answer:
(9 ^ 3) x 0.04 (4/99)
Step-by-step explanation:
This seems overwhelming, but after simplifying, it will look much easier
Numerator (First Row)
First, we will combine like terms and simplify the top row
(9 ^ <em>x</em> + 1) x 8 - (9 ^ <em>x</em> - 1) x 81
(9 ^ <em>x</em> + 1) - (9 ^ <em>x</em> - 1) x (8 x 81)
(9 ^ 2x) x 648
Denominator (Second Row)
Next, we can combine like terms and simplify the second row
(9 ^ <em>x</em>) x 66 - (9 ^ <em>x</em> - 2) x 243
(9 ^ <em>x</em>) - (9 ^ <em>x</em> - 2) x (66 x 243)
(9 ^ 2x + 2) x 16,038
Simplify
Our expression is now
(9 ^ 2x) x 648
(9 ^ 2x + 2) x 16,038
We can simplify it as
(9 ^ 3) x 0.04 (4/99)
