Question

find the squares of the following rational numbers.185​

Answer 1

$\red{ Square \:of \: 185}$

$= 185^{2}$

$= ( 200 - 15 )^{2}$

/* By Algebraic Identity */

$\boxed{ \pink { ( a - b)^{2} = a^{2} - 2ab + b^{2} }}$

$Here, a = 200 \:and \: b = 15$

$= (200)^{2} - 2 \times 200 \times 15 + 15^{2}$

$= 40000 - 6000 + 225$

$= 34000 + 225$

$= 34225$

Therefore.,

$\red{ Square \:of \: 185} \green { = 34225}$
