Answer:
(√9)^2x-1/2 = 1/81
3^2x-1/2 = 1/(3)⁴. (as √9 = 3)
3^2x-1/2 = 3^-⁴. (as 1/a^m = a^-m)
as base are equal exponents are equal
so 3 gets cancelled out
2x-1/2 = -4
(4x-1)/2 = -4
4x-1 = -8
x = -7/4
hope this helps

Answer:
1
Step-by-step explanation:
We need to find the factors of 18 and 35
Breaking into prime factors
18 = 2*9 = 2*3*3
35 = 5*7
There are no common factors so the greatest common factor is 1
