Question

A) 107 * 36 + 65 * 107 -107

B) 405 * 8 + 810 * 6 + 801

Answer 1

a) 107 x 36 + 65 x 107 - 107

= 107 x 36 + 65 x 107 - 107 x 1

= 107 x ( 36 + 65 - 1 )

= 107 x 100

= 10 700

b) 405 x 8 + 810 x 6 + 801

= không biết

Answer 2

a) \(=107\times\left(36+65-1\right)=107\times100=10700\)

b) \(=810\times4+810\times6+810=810\times\left(4+6+1\right)=810\times11=8910\)

Answer 3

    107 x 36 + 65 x 107 - 107

= 107 x 36 + 65 x 107 -107 x 1

= 107 x ( 36 + 65 - 1 )

= 107 x 100

= 10700
