Question

evaluate 988^2 using identities
​

Answer 1

Answer:

$988^2=247144$

Step-by-step explanation:

$988=900+80+8$

$988^2=(900+80+8)^2$

let us use the identity:-

$(a+b+c)^2=a^2+b^2+c^2+2ab+2bc+2ca$

$988^2=900^2+80^2+8^2+2(900)(80)+2(80)(8)+2(8)(900)$

$988^2=810000+6400+64+144000+1280+14400$

$988^2=247144$
