Question

find the value of(91)^2-(23)^2​

Answer 1

$\huge\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\pink{R}}}}$

$=> {(91)}^2 - {(23)}^2$

As

$=> {(a)}^2 - {(b)}^2 = (a+b) (a-b)$

So

$=> (91+23) (91-23)$

$=> (114) (68)$

$=> 7752 Answer.$

Answer 2

Answer:

so the answer is 7752

Step-by-step explanation:

use the formula (a^2-b^2)=(a+b)*(a-b)

here a=91,b=23

(91+23)*(91-23)=68*114=7752
