As a rule , - times - = + and - times + = -

Therefore the correct answer to the question is 2m squared n
The answer for that problem is X<26
So I think the rule is that you divide two exponents with the same base, you keep the base and subtract the powers.
70% of the trip length, t, is 35 miles. Find t:
0.70t = 35. Dividing both sides by 0.70, we get:
35
t = ----------- = 50
0.70
The total trip length is 50 miles.
