Answer:
25.5 and 37.5
Step-by-step explanation:
x+y=63
x-y = 12 then x = 12 + y sub this into the first equation
(12+y) + y = 63
12 + 2y = 63
2y = 51
y = 25.5 then x = 37.5

Answer:
x = 1/6
Step-by-step explanation:
The relevant rules of exponents are ...
(a^b)/(a^c) = a^(b-c)
(a^b)^c = a^(bc)
__
The fraction inside parentheses evaluates to ...
3^(3/4 -3/8) = 3^(3/8)
Then the whole expression evaluates to ...
(3^(3/8))^(4/9) = 3^((3/8)(4/9)) = 3^(12/72) = 3^(1/6)
The value of x is 1/6.
