Step-by-Step Solution

To solve the problem, we need to apply the power of a product rule for exponents, which states that if you have a product raised to an exponent, you can apply the exponent to each factor in the product individually.

The general form of this rule is:

(a×b)n=an×bn (a \times b)^n = a^n \times b^n

According to this formula, when we have the expression(9×7)4 (9 \times 7)^4 we apply the exponent 4 to each factor within the parentheses.

This process results in:

  • Raising 9 to the power of 4: 94 9^4

  • Raising 7 to the power of 4: 74 7^4

Therefore, the expression simplifies to:

94×74 9^4 \times 7^4

Answer

94×74 9^4\times7^4
