Question

What is the solution to the equation log sub 4 x – log sub 4 2 = 3

Answer 1

\(\Rightarrow \log_4x - {1 \over 2} = 3 \)

\(\Rightarrow \log _4 x = 2.5 \)

\(\Rightarrow x = 4^{2.5} \)

Answer 2

\(\Rightarrow x = 4^2 \times 4^{0.5} \)
\(\Rightarrow x = 16 \times \sqrt4 \)
\(\Rightarrow x = 16 \times 2 \)
\(\Rightarrow x = 32\)
