Answer:

You are correct my good sir! 7^5/7^2 expanded is (7x7x7x7x7)/(7x7)! another awesome thing to know for future reference is when dividing exponents with the same base you can simply subtract the exponents from each other! for example, 7^5/7^2=7^3! :D Hope This Helps!

Answer:

Option D is the answer.

Step-by-step explanation:

The given expression is \frac{7^{5}}{7^{2}}

We know 7^{5} = 7×7×7×7×7

and 7^{2} = 7×7

Therefore, we can rewrite the expression as \frac{7\times 7\times 7\times7 \times 7}{7\times 7} which maches with option D.

City A is 25% less than population of city B so city A's population is what % of city B
Lerok [7]

City A is 25% less than population of city B. So city A's population is 75% of city B

<h3><u>Solution:</u></h3>

Given that City A is 25% less than population of city B

To find: city A's population is what % of city B

From given information,

City A is 25% less than population of city B

A = B - 25% of B

So we can write as,

A = B - \frac{25}{100} \times B\\\\A = B - 0.25B\\\\A = 0.75B

A = 0.75B can be written as,

A = \frac{75}{100}\times B

city A = 75 % of City B

Thus city A's population is 75% of city B
