Question 270927: Find the two real-number solutions of each equation.
(ref) x^2 would represent a number squared
x^2 = 100
x^4 = 1
x^2 = 0.25
x^4 = 16/81

sqrt%28x%5E2%29=sqrt%28100%29 highlight%2810%29
x^4 = 1 highlight%281%29 1*1*1*1
sqrt%28x%5E2%29=sqrt%280.25%29highlight%280.05%29
x^4 = 16/81 this is the 4throot of 16 divided by the 4throot of 81
2%5E4%2F3%5E4=16%2F81 so taking the 4th roots makes highlight%28x=2%2F3%29
