Question

If 3x−y=12, what is the value of
8x/2y?

A) 212
B) 44
C) 82

Answer 1

Answer:

$\frac{8^x}{2^y} 2y=2x^{12}$

Step-by-step explanation:

Since the numerator and denominator have a common base, this expression can be rewritten as 2(3x−y).

substitute 12 for the exponent, 3x−y and you will get A

Answer 2

Answer:

The answer is A $2^{12}$

Step-by-step explanation:

Since 2 and 8 are both powers of 2, substituting 23 for 8 in the numerator of  

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

gives you

$\frac{8x}{2y} 2y=2x^{12}$
