解答

化简

11 (9^{2})

8111

十进制

268.64660 \dots

求解步骤

11 (9^{2})

使用法则:

(a) = a

(9^{2}) = 9^{2}

= 11 \cdot 9^{2}

9^{2} = 81

= 11 \cdot 81

= 8111

x^{2} - 6 x + 13 = 32

s im pl i f y \frac{9 a ^{4} b ^{3} - 3 a ^{3} b ^{4}}{6 a ^{3} b ^{3} - 2 a ^{2} b ^{4}}

\frac{2}{x + 2} > \frac{1}{x + 3}

2 (3 x - 4) \leq - 20

f a c t or - 16 x^{2} - 6 x^{4}
