Need asap! (plesse do a clear explanation, becuase i wanna learn how you got the answer, not plagiarize.)lin and diego travel in cars on the high at constant speeds. in each case, decide who was traveling faster and explain how you know. a: during the first half house, line travels 23 miles while diego travels 25 miles. b: after stopping for lunch, they travel at different speeds. to travel next to 60 miles, it takes lin 65 minutes and it takes deigo 70 minutes.

A) what do you mean 'half house'?

B) If they are both traveling 60 miles at a constant rate then you need to find miles/hour (miles per hour) so:

Line: M/H - 60/65 = .9

Diego: M/H 60/70 = .85

Line had the bigger number which means that he went faster.

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
