Select the equivalent expression.
Free_Kalibri [48]

Answer:

\frac{7^{15}}{3^{30}}

Step-by-step explanation:

The given expression is:

(\frac{3^{-6}}{7^{-3}})^{5}

Moving the expression to the other side in the fraction changes its sign to opposite. A numerator with negative exponent, when written in denominator will have the positive exponent. Using this rule, we can write:

(\frac{3^{-6}}{7^{-3}})^{5}\\\\ = (\frac{7^{3}}{3^{6}} )^{5}

The exponent 5 can be distributed to both numerator and denominator as shown:

(\frac{7^{3}}{3^{6}} )^{5}\\\\ = \frac{(7^{3})^{5}}{(3^{6})^{5}}

The power of a power can be written as a product. i.e.

\frac{(7^{3})^{5}}{(3^{6})^{5}}\\\\ =\frac{7^{15}}{3^{30}}

So, the expression similar to the given expression and with positive exponents is: \frac{7^{15}}{3^{30}}

A local concert promoter purchases 2 3/4 pages of ads. When one of the concerts is cancelled, the promoter cancels 1 5/8 pages o
Lynna [10]

Answer:

1\frac{1}{8} pages

Step-by-step explanation:

Since the concert promoter started with 2 \frac{3}{4} pages of ads but had to cancel 1 \frac{5}{8}, subtracting the cancelled amount from the original amount will give the amount of advertising space the promoter is now actually using:

 2 \frac{3}{4}  = 2 \frac{6}{8}

- <u>1 \frac{5}{8}</u>      - <u>1 \frac{5}{8}</u>

     1\frac{1}{8} pages

In order to subtract fractions, you need to have like denominators, so you need to convert \frac{3}{4} into an equivalent fraction with a denominator of '8'.  Since 4 x 2 = 8, then you also need to multiply the numerator by the same factor: 3 x 2 = 6.
