化简 100((b^2)/8+75(b/2+25))

解答

化简

100 (\frac{b ^{2}}{8} + 75 (\frac{b}{2} + 25))

\frac{25 b ^{2}}{2} + 187500 + 3750 b

求解步骤

100 (\frac{b ^{2}}{8} + 75 (\frac{b}{2} + 25))

化简

\frac{b ^{2}}{8} + 75 (\frac{b}{2} + 25) : \frac{b ^{2}}{8} + \frac{75 ( 50 + b )}{2}

= 100 (\frac{b ^{2}}{8} + \frac{75 ( 50 + b )}{2})

展开

100 (\frac{b ^{2}}{8} + \frac{75 ( 50 + b )}{2}) : \frac{25 b ^{2}}{2} + 187500 + 3750 b

= \frac{25 b ^{2}}{2} + 187500 + 3750 b
