Answer :
To find the square of a number means to multiply the number by itself. Let's find the square of each given number one by one. I'll use the formula [tex]x^2 = x \times x[/tex].
35: [tex]35^2 = 35 \times 35 = 1225[/tex]
18: [tex]18^2 = 18 \times 18 = 324[/tex]
21: [tex]21^2 = 21 \times 21 = 441[/tex]
27: [tex]27^2 = 27 \times 27 = 729[/tex]
34: [tex]34^2 = 34 \times 34 = 1156[/tex]
45: [tex]45^2 = 45 \times 45 = 2025[/tex]
42: [tex]42^2 = 42 \times 42 = 1764[/tex]
53: [tex]53^2 = 53 \times 53 = 2809[/tex]
69: [tex]69^2 = 69 \times 69 = 4761[/tex]
87: [tex]87^2 = 87 \times 87 = 7569[/tex]
76: [tex]76^2 = 76 \times 76 = 5776[/tex]
98: [tex]98^2 = 98 \times 98 = 9604[/tex]
These are the squares of the given numbers. Calculating squares is an important skill in mathematics as it is foundational to understanding quadratic equations, geometry, and more advanced topics.
