Exponent Notation: Note that -4 2 and (-4) 2 result in different answers: -4 2 = -1 * 4 * 4 = -16, while (-4) 2 = (-4) * (-4) = 16. If you enter a negative value for x, such as -4, this calculator assumes (-4) n. When a minus sign occurs with

Exponents. The exponent of a number says how many times to use the number in a multiplication. In 82 the 2 says to use 8 twice in a multiplication, so 82 = 8 × 8 = 64. In words:

How to Calculate Exponents

a fraction ( 1/n) part. So, because m/n = m × (1/n) we can do this: x m/n = x (m × 1/n) = (x m) 1/n = n√xm. The order does not matter, so it also works for m/n = (1/n) × m: x m/n = x (1/n × m) = (x
