Answer:
[tex]c) 82[/tex]
[tex] d) - 11[/tex]
[tex]g)27[/tex]
[tex]h)1000[/tex]
[tex]k)11[/tex]
[tex]l) 8[/tex]
Step-by-step explanation:
[tex] {9}^{2} + 1 \\ = (9 \times 9) + 1 \\ = 81 + 1 \\ = 82[/tex]
[tex] {6}^{2} - {5}^{2} \\ = (6 \times 6) - (5 \times 5) \\ = 36 - 25 \\ = - 11[/tex]
[tex](1 + 2 {)}^{3} \\ = {3}^{3} \\ = 3 \times 3 \times 3\\ = 27[/tex]
[tex](2 + 8 {)}^{3} \\ = {10}^{3} \\ = (10 \times 10 \times 10) \\ = 1000[/tex]
[tex] \sqrt{4} + {3}^{2} \\ = 2 + {3}^{2} \\ = 2 + (3 \times 3) \\ = 2 + 9 \\ = 11[/tex]
[tex]2 \times 5 - \sqrt{4} \\ = 10 - \sqrt{4} \\ = 10 - 2 \\ = 8[/tex]
