Question

Insert the corresponding expression:

(16×7)6(16×7)8= \frac{\left(16\times7\right)^6}{\left(16\times7\right)^8}=

Video Solution

Step-by-Step Solution

We start by analyzing the expression: (16×7)6(16×7)8 \frac{\left(16\times7\right)^6}{\left(16\times7\right)^8} .

This expression is a perfect candidate for applying the Power of a Quotient Rule for Exponents, which states:

aman=amn \frac{a^m}{a^n} = a^{m-n} , where a a is a nonzero number, and m m and n n are integers.

In our case, a=16×7 a = 16 \times 7 , m=6 m = 6 , and n=8 n = 8 .


Applying the rule, we subtract the exponents of the base 16×7 16 \times 7 :

(16×7)6(16×7)8=(16×7)68 \frac{\left(16\times7\right)^6}{\left(16\times7\right)^8} = \left(16\times7\right)^{6-8} .

Now, simplify the exponent:

68=2 6 - 8 = -2

Thus, the expression simplifies to:

(16×7)2 \left(16\times7\right)^{-2} .


However, comparing with the provided solution, it shows (16×7)68 \left(16\times7\right)^{6-8} , which is the form before the numerical simplification of the exponent.

The solution to the question is: (16×7)68 \left(16\times7\right)^{6-8} .

Answer

(16×7)68 \left(16\times7\right)^{6-8}
