## What Is a Perfect Square?

A perfect square is a number that can be expressed together the product of 2 equal integers.

Basically, a perfect square is what you acquire when you multiply 2 equal integers by each other.

For instance:

\$\$5 * 5 = 25\$\$

25 is a perfect square due to the fact that you’re multiplying 2 equal integers (5 and 5) by each other.

You can additionally express \$5 * 5\$ as \$5^2\$. That’s where you obtain the ax “perfect square”

## List the Perfect Squares

Here’s a list of the an initial 25 perfect squares. A hint: if you want to develop a perfect square, simply square an integer!

 Square Integers 1 \$1 * 1\$ 4 \$2 * 2\$ 9 \$3 * 3\$ 16 \$4 * 4\$ 25 \$5 * 5\$ 36 \$6 * 6\$ 49 \$7 * 7\$ 64 \$8 * 8\$ 81 \$9 * 9\$ 100 \$10 * 10\$ 121 \$11 * 11\$ 144 \$12 * 12\$ 169 \$13 * 13\$ 196 \$14 * 14\$ 225 \$15 * 15\$ 256 \$16 * 16\$ 289 \$17 * 17\$ 324 \$18 * 18\$ 361 \$19 * 19\$ 400 \$20 * 20\$ 441 \$21 * 21\$ 484 \$22 * 22\$ 529 \$23 * 23\$ 576 \$24 * 24\$ 625 \$25 * 25\$

## How come Tell If a Number Is a Perfect Square

First that all, if you develop a square by multiplying 2 equal integers by each other, climate the product is a perfect square.

So, \$1 * 1\$ is a perfect square. So is \$10 * 10\$ and also \$1,000 * 1,000\$.

You can likewise tell if a number is a perfect square by detect its square roots. recognize the square root is the station (opposite) the squaring a number.

If you uncover the square source of a number and it’s a totality integer, the tells you that the number is a perfect square.

For instance, the square root of 25 is 5. The square root of 26 is not a whole integer. So, 26 is not a perfect square.

## Key Takeaways: knowledge Perfect Squares

A perfect square is a number that have the right to be expressed as the product of two equal integers.

You can tell if a number by detect its square root and seeing if the square root is a entirety integer.
