解:500+500+500+500+500+500+500+500×500×598等于( 149503500 )
∵已知需求出500+500+500+500+500+500+500+500×500×598等于多少
X × Y + X × Z = X × ( Y + Z)
∴500 + 500 + 500 + 500 + 500 + 500 + 500 + 500 × 500 × 598
= 500 × (1 + 1 + 1 + 1 + 1 + 1 + 1 + 500 × 598)
= 500 × (2 + 1 + 1 + 1 + 1 + 1 + 299000)
= 500 × (3 + 1 + 1 + 1 + 1 + 299000)
= 500 × (4 + 1 + 1 + 1 + 299000)
= 500 × ( 5 + 1 + 1 + 299000)
= 500 × (6 + 1 + 299000)
= 500 × ( 7 + 299000)
= 500 × 299007
= 149503500
答:500+500+500+500+500+500+500+500×500×598等于149503500
