Step-by-Step Solution

The problem requires us to simplify the expression (5×7)3(5 \times 7)^3 using the power of a product rule.

The power of a product rule states that for any numbers a a and b b , and any integer n n , the expression (a×b)n (a \times b)^n can be expanded to an×bn a^n \times b^n .

Applying this rule to the given expression:

  • Identify the values of a a and b b as 5 5 and 7 7 , respectively.

  • Identify n n as 3 3 .

  • Substitute into the rule:
    (5×7)3=53×73(5 \times 7)^3 = 5^3 \times 7^3

The simplified expression is therefore: 53×735^3 \times 7^3.

Answer

53×73 5^3\times7^3
