Math Problem Statement

Find x so that (4/3)^(8x) * (4/3)^2 = (4/3)^5.

Solution

The image shows the following equation:

(43)8x×(43)2=(43)5\left( \frac{4}{3} \right)^{8x} \times \left( \frac{4}{3} \right)^2 = \left( \frac{4}{3} \right)^5

We are tasked with finding the value of xx.

Solution:

We can combine the terms on the left-hand side of the equation using the property of exponents:

am×an=am+na^m \times a^n = a^{m+n}

So, we have:

(43)8x+2=(43)5\left( \frac{4}{3} \right)^{8x + 2} = \left( \frac{4}{3} \right)^5

Now, since the bases are the same, we can equate the exponents:

8x+2=58x + 2 = 5

Now, solve for xx:

8x=528x = 5 - 2

8x=38x = 3

x=38x = \frac{3}{8}

Thus, the value of xx is 38\frac{3}{8}.
