Question

Help can u answer this

Answer 1

Answer:

$c) 82$

$d) - 11$

$g)27$

$h)1000$

$k)11$

$l) 8$

Step-by-step explanation:

${9}^{2} + 1 \\ = (9 \times 9) + 1 \\ = 81 + 1 \\ = 82$

${6}^{2} - {5}^{2} \\ = (6 \times 6) - (5 \times 5) \\ = 36 - 25 \\ = - 11$

$(1 + 2 {)}^{3} \\ = {3}^{3} \\ = 3 \times 3 \times 3\\ = 27$

$(2 + 8 {)}^{3} \\ = {10}^{3} \\ = (10 \times 10 \times 10) \\ = 1000$

$\sqrt{4} + {3}^{2} \\ = 2 + {3}^{2} \\ = 2 + (3 \times 3) \\ = 2 + 9 \\ = 11$

$2 \times 5 - \sqrt{4} \\ = 10 - \sqrt{4} \\ = 10 - 2 \\ = 8$

Hope it is helpful....
