The sum of two numbers is 52 . the larger number is 12 more than the smaller number. what are the numbers?

A) x + y = 52

B) x = y + 12 OR

B) x - y = 12

Adding the 2 equations:

2x = 64

x = 32

y = 20

answer: 32.68

step-by-step explanation:

x=2

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)
