Question

solve using identities 196*198

Answer 1

$\bold{HEY\:\: MATE!♡}$

YOUR ANSWER...

$196 \times 198$

$= (190 + 6)(190 + 8)$

By using the identity, (x+a)(x+b)=x^2+(a+b)x+ab.

$= {(190)}^{2} + (6 + 8)190 + (6 \times 8)$

$= 36100 + 14 \times 190 + 48$

$= 36100 + 2660 + 48$

$= 38808$

Hola mate !!

$<big><b>To solve using identities :- 196*198</big></b>$

196*198

= (190+6)(190+8)

Using identity ,

$<b>(x + a)(x+b) = x²+ (a+b)x + ab</b>$

190² + (6+8)190 + (6*8)

= 36100 + (190*14) + 14

= 36100 + 2660 + 14

= 38808

Thus , 196*198 = 38808
