Step-by-Step Solution

To solve the problem of rewriting the expression (6×8)4(6 \times 8)^4, we will apply the Power of a Product rule. This rule states that (a×b)n=an×bn(a \times b)^n = a^n \times b^n.

Let's apply this rule to the given expression:

(6×8)4(6 \times 8)^4 can be rewritten as 64×846^4 \times 8^4 by applying the Power of a Product rule.

Now, let's consider the choices given:

  • Choice 1: 64×846^4 \times 8^4 - This choice directly corresponds to our rewritten expression using the Power of a Product rule.

  • Choice 2: 48448^4 - This represents the product calculated first (6×8=486 \times 8 = 48) and then raised to the fourth power. This is also a valid representation since (6×8)4(6 \times 8)^4 is equivalent to 48448^4.

  • Choice 3: 64×86^4 \times 8 - This is incorrect because it does not correctly apply the Power of a Product rule.

Therefore, the correct answer according to the given choices is "a' + b' are correct," which indicates the validity of both 64×846^4 \times 8^4 and 48448^4 as representations of (6×8)4(6 \times 8)^4.

Answer

a'+b' are correct
