## Is 16 a perfect square?

Informally: When you multiply an integer (a “whole” number, positive, negative or zero) times itself, the resulting product is called a square number, or a perfect square or simply “a square.” So, 0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and so on, are all square numbers..

## Why is 4 square root 16?

For example the number 16 has a square root of 4 because 4 x 4 = 16. So when you multiply the divisor or the quotient together (or by itself – the two factors being the same) the product is the dividend (i.e. the number you are seeking to find the root of).

## Is Root 16 a SURD?

To simplify a surd, write the number under the root sign as the product of two factors, one of which is the largest perfect square. Note that the factor 16 is the largest perfect square. Recall that the numbers 1, 4, 9, 16, 25, 36, 49, … are perfect squares.

## What is the square of the 4?

4x4The square of 4 is 4×4. To show that a number is squared, a small 2 is placed to the top right of the number. Like this: These signs are the same as saying “3 squared, 4 squared, and x squared.”

## What is the square of negative 16?

√-16 = 4 i Note: since negative times negative equals positive, one could therefore conclude that -4 i is also a correct answer to the square root of negative 16.

## What is a square of 16?

256The square of 16 is 256.

## What is the positive and negative square root of 16?

So any positive real number, like 16, actually has 2 square roots, one positive, the other negative. The positive square root is termed the “principal square root,” the negative square root is unfortunately unnamed.

## Does a square root have 2 answers?

It has multiple answers so why do we pick the positive one? if x2=16⟹x=√16 or x=−√16 for respectively the positive and negative solution. This implies that the square root function has a single answer and we must negate its answer to obtain the second solution.

## What is the square of 12?
