Question

Find x,if 2^x /8=64​

Answer 1

Step-by-step explanation:

2^x/ 8= 64

=> 2^x/8 = 8^2

=> 2^x= 8^2+8^1

=> 2^x= 8^3

=> 2^x = 2^3×3

=> 2^x= 2^9

so, => X= 9

Answer 2

$\star\:\:\:\bf\underline\blue{Question:-}$

•     Find $x$ if $\frac{2^{x}}{8}=64$

$\star\:\:\:\bf\underline\blue{Solution:-}$

$\frac{2^{x}}{8}=64$

$\implies \frac{2^{x}}{2^{3}}=2^{6}$

$\implies 2^{x-3}=2^{6}$

Comparing base, we get,

$x-3=6$

$\implies x=9$
