Question

EVALUATE 93 ×107 WITHOUT MULTIPLYING directly ​

Answer 1

here 93 can be written as 100-7

also 107 as 100+7

therefore

93×107= (100-7)(100+7)

here it is in the form

(a+b)(a-b)= a2-b2

here a=100 and b=7

93×107= 100'2 - 7'2 ...

(here it means 100 power 2)

= 10000-49

= 9951

Answer 2

Answer:

Step-by-step explanation:

(100-3)(100+3)

(A+b)(a-b)=asquare-b

(100-3)(100+3)=(100*100)-(3*3)

=10000-9

=9981
