do you now the square root of 4?

Answer 1

Hi,

The square root of any number has positive and negative roots.

As you know 2 x 2 = 4 and -2 x -2 = 4, so therefore, the square root of this number is 2 and -2. This is so because these numbers when multiplied by each other (2x2 or -2x-2) both give 4.

I hope that helps you out! Please let me know if you have any other questions!

Sincerely,

Andrew

Answer 3

The square root of 4

√4 = 2

- - - - - - -s-

Answer 4

Yes I do. It's + or - 2
That's because -2 x -2 =+ 4 and +2 x +2 = +4 as well
Any number times itself yields a perfect square

Answer 5

The square root of four is 2. You can check this by making an array that is two dots by two dots. You know that four is a square because the array makes a literal square. Also, 2 times 2 gets you to four.

Answer 6

2

check: 2^2 = 2*2 = 4

It could be -2 as well, as -2^2=-2*-2=4..

Note: taking something to the power (^) is the 'opposite' of a square root.. (similar to addition is the 'opposite' of subtraction).

Answer 7

it is 2

the calculator even says its 2

since sqaure means the number times the amount of the little number called the exponent so if it is sqaured then the number times the number x times x if the number is 3 then x times x times x

so you have right now a sqaure root of 4 which means what times what is 4 in which is the same number times the same number is 4 so 2 times 2 is 4 so your answer is...

Answer 8

have a nice day

Answer 9

Is this a math question: sqrt(4)=2 ???

Or is this an epistemology question: how do we know what we know, and what does it mean to "know", especially insofar as math is concerned???

Done.

Answer 10

42, that is the answer.... you just asked the wrong question.
