Question

Solve the following with the help of appropriate formula.
1: (105)²
2: (96)³
3: (57)³
4: 104×96
5: 47×53
6: 107×93
7: 81×111​

Answer 1

Answer:

1.(105)² =105×105=11,025

2.(96)³ =96×96×96=884,736

3.(57)³ =57×57×57=185,193

4.104×96=9,984

5.47×53=2,491

6.107×93=9,951

7.81×111=8,991

Answer 2

Step-by-step explanation:

1)11025

2)884736

3)185193

4)9984

5)2491

same goes with 6th and 7th

both are in (a+b)(a-b)=( a square - b square)form

6)107×93=(100+7)×(100-7)=9951

7)I think it is supposed to be 89×111=(100-11)(100+11)...after solving the answer will be 9879
