Question

101x102 evaluate,,,,,,,,,,,,,,,,,,,,,,,,,,,,​

Answer 1

Heya!

Here is ur answer....

___________________________

= 101 × 102

= (100+1) (100+2)

_______________________

[ (x+a)(x+b)= x²+(a+b)x+ab]

-------------------------------------------

x = 100 , a = 1 , b = 2

= 100² +(1+2)100 + (1)(2)

= 10000 + (3)100 + 2

= 10000+300+2

= 10302

Hope it helps u..

Answer 2

101 × 102

= (100 + 1)(100 + 2)

We know that, (x + a)(x + b) = x² + (a + b)x + ab

Here x = 100, a = 1, b = 2

By substituting the values :

(100 + 1)(100 + 2) = 100² + (1 + 2)100 + 1(2)

= 10000 + (3)100 + 2

= 10000 + 300 + 2

= 10302

Therefore 101 × 102 = (100 + 1)(100 + 2) = 10302.
