Solution Steps

00:00 Simply
00:02 In multiplication, the order of factors doesn't matter
00:05 We'll use this formula in our exercise and switch between the factors
00:13 According to laws of exponents, division of powers with equal bases (A)
00:16 Equals the same base (A) raised to the difference of exponents (M-N)
00:21 We'll use this formula in our exercise
00:24 We'll keep the base and subtract between the exponents
00:27 This is one solution to the question
00:32 Again we'll switch between factors to find the second solution
00:36 And this is the solution to the question

Step-by-Step Solution

Let's solve the expression step-by-step using the power of a quotient rule for exponents.

The provided expression is:

(6×3)7(3×6)2 \frac{\left(6\times3\right)^7}{\left(3\times6\right)^2}

The power of a quotient rule states:

(ab)n=anbn \left(\frac{a}{b}\right)^n = \frac{a^n}{b^n}

First, simplify the terms inside the parentheses:

  • The numerator: 6×3=18 6 \times 3 = 18
  • The denominator: 3×6=18 3 \times 6 = 18

Thus, the expression simplifies to:

187182 \frac{18^7}{18^2}

We can simplify this further using the rule of dividing powers with the same base:

aman=amn \frac{a^m}{a^n} = a^{m-n}

Apply the rule:

187182=1872=185 \frac{18^7}{18^2} = 18^{7-2} = 18^5

The solution to the question is:
