Video Solution

Solution Steps

00:00 Simply
00:03 When we have a multiplication that's entirely in a certain power (N)
00:07 We can factorize and raise each factor to the power (N)
00:13 We will use this formula in our exercise
00:23 And this is the solution to the question

Step-by-Step Solution

The problem requires simplifying the expression (2×5×4)7 (2\times5\times4)^7 using the power of a product rule. According to the exponent rules, specifically the power of a product rule, we know that:

(abc)n=anbncn (a \cdot b \cdot c)^n = a^n \cdot b^n \cdot c^n

This means when we have a product raised to an exponent, each factor in the product is raised to that exponent. So let's apply this rule to the given expression:

  • First, identify the terms inside the parentheses: 2, 5, and 4.

  • Next, apply the exponent 7 to each term:

    • 27 2^7 – The first term 2 is raised to the power of 7.

    • 57 5^7 – The second term 5 is raised to the power of 7.

    • 47 4^7 – The third term 4 is raised to the power of 7.

Therefore, the expression (2×5×4)7 (2\times5\times4)^7 simplifies to:

27×57×47 2^7\times5^7\times4^7

Answer

27×57×47 2^7\times5^7\times4^7
