化简 (3/(x-2))^2+1

解答

化简

(\frac{3}{x - 2})^{2} + 1

\frac{9}{( x - 2 ) ^{2}} + 1

求解步骤

(\frac{3}{x - 2})^{2} + 1

使用指数法则:

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

(\frac{3}{x - 2})^{2} = \frac{3 ^{2}}{( x - 2 ) ^{2}}

= \frac{3 ^{2}}{( x - 2 ) ^{2}} + 1

3^{2} = 9

= \frac{9}{( x - 2 ) ^{2}} + 1

s im pl i f y \frac{x ^{- 5}}{x ^{2}}

f a c t or - 4 x^{4} - 52 x^{3} - 88 x^{2}

s im pl i f y \frac{4 - i}{4 + i}

s im pl i f y cos^{2} (x) sin (x) + sin^{3} (x)

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