hello LEXI
I believe these are the steps:
8^(1/8)
= 8^(2/16) ———–> replace 2/16 with 1/8
= (8^2)^(1/16)
= 64 ^ (1/16)
we know that,
8^(1/8) = X^(1/Y)
Substitute our previous values into this equation
64^(1/16) = X^(1/Y)
Just by observation, we can see that
X=64 and Y=16
*note: there are infinite answers to this solution. I used 2/16 to replace 1/8. We can use 3/24, 4/32, etc.
And yes, SAT can be annoying
