Question

if y^2 = 23/25 then y is what number​

Answer 1

Answer:

Y^2=23/25

=Y=+-√23/5

then y is irrational number

Answer 2

y is an irrational number.

Given,

y² = 23 / 25

To Find,

What type of number is y =?

Solution,

y² = 23 / 25

Taking root on both sides, we get

√(y²) = √(23/25)

y = ± √(23) / 5

Therefore, y can be √(23) / 5 or  - √(23) / 5.

In both cases, the √(23) is an irrational number. Therefore, y is also an irrational number.

Hence, y is an irrational number with a value ± √(23) / 5.
