How to calculate a power that is not an integer, such as 2 ^ 1.4

For example, 2 ^ 1.4:1, turn the power exponent into a fraction: 1.4 = 14 / 10 2, power exponent in the numerator: a = 2 ^ 14 (because the numerator is 14) 3, power exponent in the denominator: 2 ^ 1.4:1, power exponent in the numerator: 1.4 = 14 / 10 2, power exponent in the numerator: a = 2 ^ 14 (because the numerator is 14)
