Question

55-(√9×√4+1)^2+(4^2+3^2):5^2-1^6​

Answer 1

Olá!

55 - (√9 × √4 + 1)² + (4² + 3²) ÷ 5² - 1^6 =

55 - (3 × 2 + 1)² + (16 + 9) ÷ 5² - 1 =

55 - (6 + 1)² + 25 ÷ 5² - 1 =

55 - 7² + 5² ÷ 5² - 1 =

55 - 7² + 1 - 1 =

55 - 49 =

$\boxed{6}$

Espero ter ajudado! :)

Answer 2

$55 - ( \sqrt{9} \times \sqrt{4} + 1) ^{2} + ( {4}^{2} + {3}^{2} ) \div {5}^{2} - {1}^{6} \\ 55 - (3 \times 2 + 1) ^{2} + (16 + 9) \div 25 - 1 \\ 55 - (6 + 1) ^{2} + 25 \div 25 - 1 \\ 55 - (7) ^{2} + 1 - 1 \\ 55 - 49 \\ 6$
