Using the identity -a-b-a-x2212-b-a2-x2212-b2We can write- 107-100-7 and 93-100-x2212-7-after using formula we get- -100-7-100-x2212-7- - 1002-x2212-72-xA0-10000-x2212-49 - 9951Hence the answer is 9951

Use appropriate formula to compute $107 \times 93$

Using the identity $(a + b) (a - b)$ = $a^{2} - b^{2}$
We can write: $107 = 100 + 7$ and $93 = 100 - 7$
after using formula we get: $(100 + 7) (100 - 7)$ = $100^{2} - 7^{2}$ $= 10000 - 49$ $=$ $9951$
Hence the answer is $9951$

Use appropriate formula to compute 107×93

Using the identity (a+b)(a−b)=a2−b2We can write: 107=100+7 and 93=100−7 after using formula we get: (100+7)(100−7) = 1002−72 =10000−49 = 9951Hence the answer is 9951
