化简

(\frac{1}{2})^{20}

\frac{1}{1048576}

十进制

9.53674 E - 7

求解步骤

(\frac{1}{2})^{20}

使用指数法则:

(\frac{a}{b})^{c} = \frac{a ^{c}}{b ^{c}}

= \frac{1 ^{20}}{2 ^{20}}

1^{20} = 1

= \frac{1}{2 ^{20}}

2^{20} = 1048576

= \frac{1}{1048576}

- x \leq 15 - 2 x

3 (1 - x) + 2 x = 3 (x - 7)

f a c t or 6800 d^{2} + 1125 d - 5832

f a c t or a^{2} + a - 72

5 x^{2} + 13 x = 6
