factor(x^6 + 36 - 100)
(x - 2)*(x + 2)*(x^2 + 2*x + 4)*(x^2 - 2*x + 4) = 0
x1 = 2, x2 = - 2
x^2 + 2*x + 4 = 0
x3 = - 1 + i*sqrt(3), x4 = - 1 - i*sqrt(3)
x5 = 1 + i*sqrt(3), x6 = 1 - i*sqrt(3)
(x - 2)*(x + 2)*(x^2 + 2*x + 4)*(x^2 - 2*x + 4) = 0
x1 = 2, x2 = - 2
x^2 + 2*x + 4 = 0
x3 = - 1 + i*sqrt(3), x4 = - 1 - i*sqrt(3)
x5 = 1 + i*sqrt(3), x6 = 1 - i*sqrt(3)

x^6 + 36 = 100
x^6 = 64
x = 6√100
I don't have a calculator with me but just put it into your calculator for the answer!
x^6 = 64
x = 6√100

Real solutions:
x^6 + 36 = 100
x^6 = 100 - 36
x^6 = 64
x = ±64^(1/6)
x = ±(2^6)^(1/6)
x = ±2^(6 * 1/6)
x = ±2
x^6 + 36 = 100
x^6 = 100 - 36
x^6 = 64
x = ±64^(1/6)
x = ±(2^6)^(1/6)
x = ±2^(6 * 1/6)
x = ±2
