f. 45
g. 42
h. 53

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].

  1. 35: [tex]35^2 = 35 \times 35 = 1225[/tex]

  2. 18: [tex]18^2 = 18 \times 18 = 324[/tex]

  3. 21: [tex]21^2 = 21 \times 21 = 441[/tex]

  4. 27: [tex]27^2 = 27 \times 27 = 729[/tex]

  5. 34: [tex]34^2 = 34 \times 34 = 1156[/tex]

  6. 45: [tex]45^2 = 45 \times 45 = 2025[/tex]

  7. 42: [tex]42^2 = 42 \times 42 = 1764[/tex]

  8. 53: [tex]53^2 = 53 \times 53 = 2809[/tex]

  9. 69: [tex]69^2 = 69 \times 69 = 4761[/tex]

  10. 87: [tex]87^2 = 87 \times 87 = 7569[/tex]

  11. 76: [tex]76^2 = 76 \times 76 = 5776[/tex]

  12. 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.
