00:02 When there is an exponent on a product of terms, all terms are raised to that exponent

Step-by-Step Solution

We use the power law for multiplication within parentheses:

(x⋅y)n=xn⋅yn (x\cdot y)^n=x^n\cdot y^n

We apply it to the problem:

(4⋅7⋅3)2=42⋅72⋅32 (4\cdot7\cdot3)^2=4^2\cdot7^2\cdot3^2

Therefore, the correct answer is option a.

Note:

From the formula of the power property mentioned above, we understand that we can apply it not only to the multiplication of two terms within parentheses, but is also for multiple terms within parentheses.

Answer

42×72×32 4^2\times7^2\times3^2
