Answer 1

Answer:Hi!!

Your answer to this question will be;-

× = 9604(Ans)

Step-by-step explanation:

√x + 43 = √19881

=> √x = 141 - 43

=> √x = 98

=> x = 98 × 98

=> x = 9604(Ans)

HOPE YOU GOT THE ANSWER.

MARK ME BRAINLIEST.

THANKYOU:)

Answer 2

• Consider the Unknown value be x (Replace "?" with "x")

$\sf{\sqrt{x}+43=\sqrt{19881}}$

$\implies\sf{\sqrt{x}+43=\sqrt{141^2}}$

$\implies\sf{\sqrt{x}+43=141}$

$\implies\sf{\sqrt{x}+43-43=141-43}$

$\implies\sf{\sqrt{x}=98}$

Squaring Both Sides

$\implies\sf{\left(\sqrt{x}\right)^2=98^2}$

$\implies\sf{x=9604}$
