The sum is 160/(1-r)=1280 where r is the common ratio,
1/(1-r)=1280/160=8
Inverting we get 1-r=1/8, r=7/8.
Answer:
I'm not sure but I think the answer is 2187 X^ (14) Y^ ( 42)

Use PEMDAS to solve
(Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction)
Solve parenthesis first
<span>(1/3+9) x ( 8-3)
</span>28/3 x 5
Use Multiplication
28/3 x 5 ≈ 4.7
After rounding 4.7 should be your answer
