Answer 1

$140 \sqrt{x + 315} = 1015 \\ \\ {140}^{2} = 19600 \\ \\ {140}^{2} \: will \: go \: inside \:the\: root \\ \\ \sqrt{19600 + x + 315} = {1015} \\ \\ \sqrt{19915 + x} = {1015} \: \\ \\ 19915 + x = 1,030,225 \: \\ x = 1030225 - 19915 \\ x = 1,010,310 \: \\ \\ \\ </p><p>$

GIVEN IS 140 ROOT X+315=1015

THAT IS 140 ROOT X=1015–315=700

IE 140 ROOTX=700

ROOT X= 700/140=5

SQUARRING BOTH SIDES WE HAVE

ROOT * ROOTX=5*5

X=5*5=25

ANS IS 25.
