fraction numerator open parentheses 2 to the power of 5 close parentheses cubed 2 to the power of short dash 7 end exponent over denominator 2 to the power of short dash 6 end exponent end fraction

a.) 2 to the power of 15

b.) 2 to the power of 9

c.) 2 to the power of 8

d.) 2 to the power of 14

Solution

We are asked to simplify the expression:

(25)32726\frac{(2^5)^3 \cdot 2^{-7}}{2^{-6}}

Step-by-step simplification:

  1. Simplify the numerator:
    Use the property of exponents: (am)n=amn(a^m)^n = a^{m \cdot n}.
    So, (25)3=253=215(2^5)^3 = 2^{5 \cdot 3} = 2^{15}.
    Therefore, the numerator becomes:
    215272^{15} \cdot 2^{-7}

  2. Combine the terms in the numerator:
    Use the rule aman=am+na^m \cdot a^n = a^{m+n}.
    So,
    21527=215+(7)=282^{15} \cdot 2^{-7} = 2^{15 + (-7)} = 2^{8}

  3. Simplify the denominator:
    The denominator is 262^{-6}.

  4. Now simplify the entire fraction:
    2826\frac{2^8}{2^{-6}} Use the rule aman=amn\frac{a^m}{a^n} = a^{m-n}.
    So,
    2826=28(6)=28+6=214\frac{2^8}{2^{-6}} = 2^{8 - (-6)} = 2^{8 + 6} = 2^{14}

Thus, the simplified expression is:

2142^{14}

Final Answer:

The correct answer is d.) 2142^{14}.
