Answer:
Question (a)
Given equation:
8 can be written as
32 can be written as
Therefore, we can rewrite the equation with base 2:
------------------------------------------------------------------------------
Question (b)
To solve:
Apply the exponent rule :
:
Subtract from both sides:
Is this 8^(2x) = 32^(x+3)?
Yup
