If 3x-y=123x−x=123, x, minus, y, equals, 12, what is the value of \frac{8^x}{2^y} 2 y 8 x start fraction, 8, start superscript

nlexa [21]

Answer:

$\frac{8^x}{2^y}$ = 4096

Step-by-step explanation:

Rules:

$\frac{a^m}{a^n}=a^{m-n}$
$a^m\times a^n= a^{m+n}$
$(a^m)^n=a^{m\times n}$

Given that,

3x-y =12

Therefore

$\frac{8^x}{2^y}$

$=\frac{(2^3)^x}{2^y}$ [ since $8=2^3$ ]

$=\frac{2^{3x}}{2^y}$ [ applying 3rd rule]

$=2^{3x-y}$ [ applying 2nd rule]

$=2^{12}$ [ since 3x-y =12]

=4096
