Question

Evaluate
(a) 38 (square)-372 (square)​

Answer 1

Step-by-step explanation:

$\Huge\red{\mathfrak{ Answer }}$

38^2-372^2

Using the identity a^2-b^2= (a+b)(a-b)

we have

(38+372)(38-372)

= 410(--234)

= -95940

hope it helps ✌

Answer 2

$(38)^2-(372)^2$

We know that , $a^2-b^2=(a+b)(a-b)$

Hence,

$(38)^2-(372)^2=(38+372)(38-372)\\\\=(410)(-334)\\\\=-136940$
