Question

1) Find the value by
6) 36 X 105
7) 72 X 90
8) 45 X 352
9) 25 X 89 +8
10) 62 X 143 - 62 X 43
11) 54 X(-98) + 54 X (-2)​

Answer 1

Step-by-step explanation:

6. 36 X 105=36x(100+5)=36x100+36x5=3600+180

=3780

7. 72 X 90=72x(100-10)=72x100-72x10

=7200-720=6480

10. 62 X 143 - 62 X 43=62x(143-43)=62x100=6200

11. 54 X(-98) + 54 X (-2)=54x(-98-2)=54x-100

= -5400
