有负数和步的指数计算器。
*使用e表示科学计数法。例如:5e3、4e-8、1.45e12
**要从基数和指数结果中找到指数,请使用对数计算器:
该指数计算公式为:
a n = a×a×n次×a
将基数a提升为n的幂,等于a的n倍。
例如:
25 = 2×2×2×2×2 = 32
an ⋅ am = an+m
实施例:2 3 ⋅2 4 = 2 (3 + 4) = 2 7 = 128
an ⋅ bn = (a ⋅ b) n
实施例:3 2 ⋅4 2 =(3⋅4)2 = 12 2 = 144
an / am = an-m
an / bn = (a / b) n
例子: 82 / 22 = (8/2)2 = 42 = 16
(an)m = an⋅m
例子: (23)4 = 2(3 ⋅ 4) = 212 = 4096
m√(an) = an/m
例子: 2√(26) = 2(6 / 2) = 23 = 8
a -n = 1 / a n
例子: 2-3 = 1 / 23 = 1 / 8 = 0.125
a 0 = 1
例子: 40 = 1
