Answer 7

\(4^x=8^4\)

\(2^{2x}=2^{12}\)

\(2x=12\)

\(x=6\)

Answer 8

\(4^x=8^4\)    \(2^{2x}=2^{3.4}\)   \(2^{2x}=2^{12}\)

=>2x=12     x=12:2=6

\(4^x=32^{24}\)    \(2^{2x}=2^{5.24}\)  \(2^{2x}=2^{120}\)

=>2x=120   x=120:2=60

\(8^x=16^{12}\)    \(2^{3x}=2^{4.12}\) \(2^{3x}=2^{48}\)

=>3x=48  x=48:3=16

\(16^x=32^8\)  \(2^{4x}=2^{5.8}\)

\(2^{4x}=2^{40}\)

=>4x=40   x=40:4=10

\(32^x=16^{10}\)  \(2^{5x}=2^{4.10}\)

\(2^{5x}=2^{40}\)

=>5x=40   x=40:5=8
