Answer 1

Step-by-step explanation:

1) 768×99

= 76,032.

2) 165×218+165×782

according to bodmas we will do multiplication first. Therefore, 35970+129030

35970+129030 =165,000.

3) 27+27×29

27+27×29 =27+783

27+27×29 =27+783 =810.

4) 40×35×125×150

40×35×125×150 =1400×18,750

40×35×125×150 =1400×18,750 =2,62,50,000.
