Apiece of cloth costs 200 if the piece was 5m longer and the cost of each metre of cloth was 2 the cost of the piece would have remained unchanged. how long is the piece and what is its original price per metre

95metres for the length and the original cost is 2.105

Step-by-step explanation:

Let the initial length be x,

So, x+5=200/2

x+5=100

x=95

Note since the total price is the same and the original length is 95metres.

Therefore, the original cost per metre is

200/95=2.105

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)
