Math Problem Statement

find 4 upon 7 into 2 upon 3 where 2 and 3 are given power of 2 divided by 4 upon 9 into 4 upon 7 where both 4 and 7 are given power of 3 use laws of exponents

Solution

To solve the expression using the laws of exponents, we'll break it down step by step.

Problem:

You are asked to find:

(47)×(2232)(439)×(4373)\frac{\left(\frac{4}{7}\right) \times \left(\frac{2^2}{3^2}\right)}{\left(\frac{4^3}{9}\right) \times \left(\frac{4^3}{7^3}\right)}

Step 1: Simplify the numerator

The numerator is:

(47)×(2232)=4×47×9=4×47×9\left(\frac{4}{7}\right) \times \left(\frac{2^2}{3^2}\right) = \frac{4 \times 4}{7 \times 9} = \frac{4 \times 4}{7 \times 9}

This simplifies to:

4×47×9\frac{4 \times 4}{7 \times 9}

Step 2: Simplify the denominator

The denominator is:

439×4373=43×439×73\frac{4^3}{9} \times \frac{4^3}{7^3} = \frac{4^3 \times 4^3}{9 \times 7^3}

Step 3: Combine the fractions

Now, the entire expression becomes:

4×47×943×439×73=4×47×9×9×7343×43\frac{\frac{4 \times 4}{7 \times 9}}{\frac{4^3 \times 4^3}{9 \times 7^3}} = \frac{4 \times 4}{7 \times 9} \times \frac{9 \times 7^3}{4^3 \times 4^3}

Step 4: Simplify using the laws of exponents

Let's simplify each part:

  1. Simplify the powers of 4: 443=4143=413=42\frac{4}{4^3} = \frac{4^1}{4^3} = 4^{1-3} = 4^{-2}

  2. Simplify the powers of 7: 773=7173=713=72\frac{7}{7^3} = \frac{7^1}{7^3} = 7^{1-3} = 7^{-2}

So the expression simplifies to:

42×72×994^{-2} \times 7^{-2} \times \frac{9}{9}

Since 99=1\frac{9}{9} = 1, we are left with:

42×724^{-2} \times 7^{-2}

Step 5: Convert back to positive exponents

42×72=142×172=116×149=17844^{-2} \times 7^{-2} = \frac{1}{4^2} \times \frac{1}{7^2} = \frac{1}{16} \times \frac{1}{49} = \frac{1}{784}

Thus, the final simplified expression is:

1784\frac{1}{784}
