in the diagram below, aabc ~ adec. what is the value of x?
24 - x
o a a

3

Step-by-step explanation:

25/5 = 18-x/x

25x = 5(18-x)

25x = 90-5x

30x =90

x = 90/30

x = 3

आशा है कि मैंने मदद की

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)
