Video Solution

Solution Steps

00:00 Simplify the following problem
00:04 When we are presented with a multiplication operation where all the factors have the same exponent (N)
00:09 Each factor can be raised to the power (N)
00:13 We will apply this formula to our exercise
00:22 In multiplication, the order of factors doesn't matter, therefore the expressions are equal
00:31 We will apply this formula to our exercise, and change the order of factors
00:53 This is the solution

Step-by-Step Solution

To solve the given problem, we'll utilize the power of a product rule. This rule states that:

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

Let's apply this rule to the expression (9×6×8)5(9 \times 6 \times 8)^5:

(9×6×8)5=95×65×85 (9 \times 6 \times 8)^5 = 9^5 \times 6^5 \times 8^5

It's important to note that when using this rule, the order of terms under multiplication does not affect the result due to the commutative property of multiplication. Thus, any permutation of the factors yields the same mathematical value. Hence, the expression can also be written as:

  • 85×65×95 8^5 \times 6^5 \times 9^5
  • 85×95×65 8^5 \times 9^5 \times 6^5
  • 95×85×65 9^5 \times 8^5 \times 6^5

Upon reviewing the answer choices, each choice represents a valid permutation of 95×65×85 9^5 \times 6^5 \times 8^5 .

This leads us to conclude that all given options are correct, including the explicit choice stating this fact.

Therefore, the solution to the problem is: All answers are correct.
