Intrastate 70 stretches almost 2 ^ 3 * 5 ^ 2 * 11 miles across the united states. about how many miles long is the interest 70?

(2)^3 * (5)^2 * 11

We use PEMDAS so we have to do the exponents first.

2^3 = 8

5^2 = 25

8 * 25 *11

You then go left to right cause they are all multiplication:

200 *11 = 2200 miles

entering that problem on the tube might get you an answer

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
