Answer:

$\frac{3x^6}{6x^{-1}}= \frac{1}{2}x^7$

Step-by-step explanation:

Given

$\frac{3x^6}{6x^{-1}}$

Required

Solve

In laws of indices, we have:

$\frac{x^m}{x^n} = x^{m-n}$

So, the expression becomes:

$\frac{3x^{6 - (-1)}}{6}$

$\frac{3x^{6 +1}}{6}$

$\frac{3x^7}{6}$

Divide 3 and 6 by 3

$\frac{1x^7}{2}$

$\frac{x^7}{2}$

This can be rewritten as:

$\frac{1}{2}x^7$

Hence:

$\frac{3x^6}{6x^{-1}}= \frac{1}{2}x^7$

Team rise over run canoed 15 3/4 miles in 2 1/4 hours what was the average rate of speed in miles per hour

frosja888 [35]

Hi there! To do this, we can divide both fractions. We have to convert the fractions into improper fractions. 15 3/4 (63/4) and 2 1/4 (9/4). To divide fractions, keep the first fraction the same, change division into multiplication, and flip the second fraction over. 63/4 * 4/9 is 252/36 or 7 when simplified. The average rate of speed was 7 miles per hour.
