integral from 0 to 1 of \sqrt[4]{x}
Let's integrate: ∫01x4dx
We integrate x4 by applying: ∫xndx = xn + 1n + 1
ⓘ An antiderivative of x^n is x^(n+1)/(n+1), for n ≠ -1: ∫x4dx = x5454
x5454
ⓘ Dividing is multiplying by the reciprocal: x5454 = x54·45
x54·45
ⓘ Multiplying a fraction by a term multiplies its numerator: x54·45 = x54·45
▷ x54·45
Let's evaluate for the interval [0, 1]: 4·1545 -4·0545
ⓘ A product with a zero factor is zero: 4·0 = 0
45 + 0
ⓘ Adding 0 changes nothing: 45 + 0 = 45
▶Integral:   45
The numeric value of: 45 is:
▷ 0.8
