Question

Sum of a number and its positive square root is 6/25 find the number

Answer 1

Answer:

Let the number be x.

By the given condition,

X+√x=6/25.............1

Let√x=y.t

Therefore X=y^2.

From 1

y^2+y=6/25.

25y^2+25y-6=0

By factorising we get y=1/5,-6/5.

Since negative value is not valid

y=1/5.

√x=y

x=1/25.
