Answer 1

Answer:

x = 7

Step-by-step explanation:

given, 2³ * 2⁴ = 2ˣ

       => 2⁽³⁺⁴⁾ = 2ˣ

       => x = 3+4

       =>  x = 7

Answer 2

$\rm{2^3\times \:2^4=2^x}\longrightarrow\rm{2^{3+4}=2^x}$

$\longrightarrow\rm{2^{7}=2^x}\longrightarrow\rm{x=7\quad...Since\:f\left(x\right)=g\left(x\right)\:when\:a^{f\left(x\right)}=a^{g\left(x\right)}}$
