What would f(x)=

Question

Express the function f(x)=log 2 (8^ 2x+9 16^ 9x+3 ) without logarithms . f(x)=

Answer 1

log₂(8^2x+916^9x+3) = log₂[(2³)^2x+9(2⁴)^9x+3] = log₂[2^6x+272^36x+12] = log₂[2^42x+39] = 42x+39

Answer 2

Could you write the question with required brackets? it's not clear to me!
