In today's class we will learn the topic Squares of numbers
Squares of number
Square of number is the value we get when we multiply a number by itself.
For example
5 × 5 = 25
4 × 4 = 16
From the above examples, 25 and 16 are square numbers because they were gotten from multiplying 5 and 4 by themselves.
Square is representation by a tiny digit above a number. Example: 3 2 , The tiny two above the 3 shows that the number 3 is to be doubled or multiplied by itself to get a square number.
Square numbers between 1-100
The box above contains square numbers that are between the range of 1-100.
Example 1
Let's say we are asked to find the square of the following numbers:
(a). 50
(b). 20
Solution
a). Multiply 50 by itself
502 = 50 × 50 = 2500
This means that the square of 50 is 2500 because we multiplied 50 by itself to 2500 which is the square number
b). Multiply 20 by itself
202 = 20 × 20 = 400
the square of 20 is 400 because we multiplied 20 by itself to 400 which is the square number
Example 2
Find the square of the following
Steps to find the solution:
- Raise both the denominator and numerator by the square of 2.
Example:
52/22.
- Multiply the numerator by itself and also the denominator by itself to get the values. The value you get will be the square numbers
Find the value of the following number:
1. 72 + 4 2
2. 142-102
Step to solve the problem
Simplify the numbers raised to the square/power of two.
- Add the first number to the second. Example is shown below:
Solution 1
72 + 4 2
= (7 × 7) + (4 × 4)
= 49 + 16 = 65
Solution 2
142-102
(14 × 14) - (10 × 10)
= 196 - 100 = 96
Assignment

2. Simplify the following
152 + 52
122 - 62
