Can a triangle be formed with the following measurements?: 4 m, 5.1 m, 12.5 m

no

Step-by-step explanation:

Hello There!

So in order for it to be a triangle the sum of the two shorter sides has to be greater than the longest side

4+5.1=9.1

9.1 is not greater than 12.5 therefore a triangle cannot be formed with the given measurement

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)
