If you use a calculator, (-2 3)to power of 2 is also 12. For sqrt of a positive number you will also get two answers. This is because when you square a negative number, the negative signs will multiply each other to give a positive answer. What my previous answer did was to explain how to get exact answer by taking out 4 ,what calculator shows is the decimal answer.
This answer has been flagged as incorrect.

I don't actually get how is my answer wrong.

The simplified form of sqrt 12 is 2 sqrt 3 , that's right but the value of sqrt 12 is 3.46.. How is that wrong ?

@yeswey can you explain please ?
both the positive and negative numbers are the square roots of a number
You didn't get what i am trying to say . The Square root of twelve is 3.46410 which is my answer.

Your answer is merely the simplified form of square root of 12 and not the actual value.

you can get the approximate value in decimal form but you missed the negative value.
That's not even a valid reason for flag . The square root of 12 is positive 3.46410 and not negative.

This is an unnecessary flag yeswey.
Yeswey is correct.

@andrew the answer she gave 2 sqrt 3 simply means 3.4641 which is the real root which is also supported by your link .

I fail to understand how is 2 sqrt 3 correct and its value 3.4641 isn't .

When you simplify 2 sqrt 3 it is 3.4641 .

It's like her answer is 4/2 which is correct and mine is 2 so it's incorrect.

It says Decimal approximation: 3.4641...... which is my answer
