Question

21
140 7 215 = 1015. - 27
$140 \sqrt{x} + 315 = 1015 then \: find \: x$
​

Answer 1

GIVEN IS 140 ROOT X+315=1015

THAT IS 140 ROOT X=1015–316=700

IE 140 ROOTX=700

ROOT X= 700/140=5

SQUARRING BOTH SIDES WE HAVE

ROOT * ROOTX=5*5

X=5*5=25

Answer 2

Answer:

x=25

Step-by-step explanation:

140×square root of x +315 =1015

take 315 to other side

140×square root of x =1015-415=700

then take 140 to other side

square root of x =700÷140=5

now to find the answer to this square both the sides

to x square root when square gives x

5 square is 25

so you will get x=25
