Answer» -step EXPLANATION:One approach is to express8x2yso that the numerator and denominator are expressed with the same base. Since 2 and 8 are both powers of 2, SUBSTITUTING 23 for 8 in the numerator of 8x by 2y giveswhich can be rewritten2^3x by 2ySince the numerator and denominator of have a common base, this expression can be rewritten as 2(3x−y). In the QUESTION, it states that 3x−y=12, so one can substitute 12 for the exponent, 3x−y, which means that8x by 2y=2^12THE FINAL ANSWER IS (A) |
