Step-by-Step Solution

To solve the given expression, we apply the Power of a Quotient Rule for Exponents. This rule tells us that if we have an expression of the form bmbn \frac{b^m}{b^n} , it simplifies to bmn b^{m-n} .


Given the expression (2×a)5(2×a)3 \frac{(2\times a)^5}{(2\times a)^3} , we can identify it with the rule as follows. Here, the base (2×a) (2\times a) is the same in both the numerator and the denominator, with exponents 5 and 3 respectively.


According to the rule, we subtract the exponent in the denominator from the exponent in the numerator, which results in (2×a)53 (2\times a)^{5-3} .


This simplifies to (2×a)2 (2\times a)^2 , but based on the way the answer is expected to be expressed, we stick with (2×a)53 (2\times a)^{5-3} .


Thus, the solution to the question is: (2×a)53 (2\times a)^{5-3}

Answer

(2×a)53 \left(2\times a\right)^{5-3}
