Intermediate Test Prep (Grades7-8) Perfect Squares

The product of a number and itself is a perfect square. We use 2 as our exponent to square a number (also known as finding the square root of a number).

Consider the table below...

Number	Work	Perfect Square
0	0x0 or 0²	0
1	1x1or 1²	1
2	2x2 or 2²	4
3	3x3 or 3²	9
4	4x4 or 4²	16
5	5x5 or 5²	25
6	6x6 or 6²	36
7	7x7 or 7²	49
8	8x8 or 8²	64
9	9x9 or 9²	81
10	10x10 or 10²	100

Let's continue our perfect squares...

Example: Square the numbers 11 to 15 and list the perfect squares.

Number	Work	Perfect Square
11	11x11 or 11²	121
12	12x12 or 12²	144
13	13x13 or 13²	169
14	14x14 or 14²	196
15	15x15 or 15²	225

Remember:

To find the perfect square of a number

multiply the number by itself.
