e x p ress i o n^{0.15} k (x + y)

i (7.38905 \dots p k n^{0.15} x^{2} r s^{2} o + 7.38905 \dots p k n^{0.15} x r s^{2} oy)

求解步骤

e x p ress i o n^{0.15} k (x + y)

= ee i p k n^{0.15} x rsso (x + y)

使用分配律:

a (b + c) = ab + a c

a = e x p ress i o n^{0.15} k, b = x, c = y

= e x p ress i o n^{0.15} k x + e x p ress i o n^{0.15} k y

= ee i p k n^{0.15} xx rsso + ee i p k n^{0.15} x rssoy

化简

ee i p k n^{0.15} xx rsso + ee i p k n^{0.15} x rssoy : i (7.38905 \dots p k n^{0.15} x^{2} r s^{2} o + 7.38905 \dots p k n^{0.15} x r s^{2} oy)

= i (7.38905 \dots p k n^{0.15} x^{2} r s^{2} o + 7.38905 \dots p k n^{0.15} x r s^{2} oy)

e x p an d (2 x + y^{3} - 3)^{5}

e x p an d \frac{sin ^{2} ( x )}{x ( 1 - e ^{x} )}

e x p an d 64 t^{2} \cdot 9 t + 2

e x p an d sin (2 (ln (5 x + 1) - 1))

e x p an d (981 - 2 t) \frac{d x}{d t}
