Question

If a²=23/25 than a is
a)rational b)irrational c)whole number d)integer

Answer 1

Answer:

a^2=23/25

a=√23/√25

a=√23/5

So, a will be an irrational number.

Hence, option B is correct.

Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

If a²=23/25 than a is

a)rational

b)irrational

c)whole number

d)integer

EVALUATION

Here it is given that

$\displaystyle \sf \: {a}^{2} = \frac{23}{25}$

$\displaystyle \sf \implies a = \sqrt{\frac{23}{25} }$

$\displaystyle \sf \implies a = \frac{ \sqrt{23} }{5}$

So the number can not written in the form p/q where p and q are integers with q ≠ 0

Hence the number is not rational

So the number is irrational

FINAL ANSWER

Hence the correct option is b) irrational
