The area of a triangle may be determined by using the formula a = (1/2)bh, where "a" stands for area, "b" stands for the length of the base of the triangle, and "h" stands for the height of the triangle. if the base of the triangle measures 7 cm and the height of the triangle measures 4 cm, what is the area of the triangle?

14 cm

step-by-step explanation:

because 7*4=28

28/2=14

we don't have enough info to solve this

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)
