Question

What is the real numbers for a, radical a squared

Answer 1

`\sqrt{a^(2)}` = a

Explanation:

We have to evaluate the expression, 'Radical a squared'.

Now, radical means square root.

So, our expression becomes, 'Square root of 'a' square'.

That is, the expression is
`\sqrt{a^(2)}`.

We know that, the square root of some squared value is the value itself.

So,
`\sqrt{a^(2)}` = a

Hence, the real number for 'radical a squared' i.e.
`\sqrt{a^(2)}` is 'a'.
