True or False, Sqrt9 + 3 = 0?

Question

True or False, Sqrt9 + 3 = 0?

Answer 1

False. Sq rt 9 = 3

3+3 not 0

Answer 2

False.

SQRT(9) usually refers to the positive square root of 9, which is 3.

Answer 3

It is both true and false.

sqrt(9) + 3 =

-3 + 3 = 0

or 3+3=6

Therefore, the answer is sqrt(9)+3=0 or 6

Answer 4

it can do

-3 squared is 9

-3+3=0

:)

Answer 5

Yes that can be true because the square of both a positve number and a negative number are the same. For example the square of 4 is 16 and the square of -4 is also 16.

So in this question the square root of 9 could be either 3 or -3. Let's say in this case it is -3.

-3 + 3 = 0

So it would be True.

I think this question is a trick question for you to get you to realise that the square root of a number can be both positive or negative.

Answer 6

±√( 9 ) + 3 ? 0

- √( 9 ) + 3 = 0
