化简 (2^5)/(2^2)

解答

化简

\frac{2 ^{5}}{2 ^{2}}

8

求解步骤

\frac{2 ^{5}}{2 ^{2}}

使用指数法则:

\frac{x ^{a}}{x ^{b}} = x^{a - b}

= 2^{5 - 2}

2^{5 - 2} = 8

= 8

x + 5 < x - 3 < \frac{1}{2} x + 1

∣ (x + 1) (x + 3) ∣ < \frac{x}{2} + 2

- 2 y > 40

f a c t or 3 n^{2} + 8 n - 3

s im pl i f y (98 d)^{\frac{1}{2}}
