8^(x - 2a) = 1/2^(5a)
2^a = 8^x
x = a/3
Answer choice:
x=1/3a
2^a = 8^x
x = a/3
Answer choice:
x=1/3a

8 = 2^3
1/2 = 2^(-1)
Now rewrite the equation
2^(3*(x-2a)) = 2^(-1*(5a))
Can you take it from there? Just make the exponents equal on both sides.
1/2 = 2^(-1)
Now rewrite the equation
2^(3*(x-2a)) = 2^(-1*(5a))
Can you take it from there? Just make the exponents equal on both sides.
