Question

Evaluate the principle square of 81.

Answer 1

The square of a number is equal to the number times itself:
\[81^2=81 \times 81\]

Answer 2

Waaaa?

Answer 3

If you want to square a number, you multiply it by itself. So 2 squared is 2x2. 3 squared is 3x3. And so on. So 81 squared is 81x81

Answer 4

The principle square of a number is its positive square root. So that of 81 would be 9.

Answer 5

Is the question asking for the square or square root @xxmarcusxx1994 ? From the way you wrote it, it's asking for the square.

Answer 6

So 9? i typed it liked it is

Answer 7

If the question doesn't say root, then it's not asking for the root. So I would say the answer is 81x81=6561. But as it's written, it's a little awkward and ambiguous.

Answer 8

Square and Square root 2 different things?

Answer 9

Yes. Very different.

Answer 10

Yes, I would actually agree @vinnv226 . Does the question let you know if you are right or wrong? @xxmarcusxx1994

Answer 11

Well yea add root

Answer 12

Yes, they are most certainly different. The square of a number = itself x itself, such as 3x3. The square root of a number = two identical numbers multiplied together to give that number, like the square root of 9 is + or - 3. A square is always +, while a square root may be positive or negative.

Answer 13

So in this case the answer is 9.

Answer 14

Thanxx ^_^
