298565

Step-by-step explanation:

Given problem,

1415 * 211

∵ Direct multiplication is quite tough so we can split the number into smaller one for making the multiplication easier,

= (1400 + 15) * (210 + 1)

By using distributive property,

= 1400 * (210 + 1) + 15 (210 + 1)

Again by distributive property,

= 1400 * 210 + 1400 + 15 * 210 + 15

Simplifying,

= 294000 + 1400 + 3150 + 15

= 298565

Hence, 1415 * 211 = 298565
