Question

Calcule as expressões abaixo :
​

Answer 1

Resposta:

a) -21

b) 4,536

c) 10,421

d) 54,4003

e) 19,16

Explicação passo-a-passo:

a) (√16 +3) - (6√25-2)

(4+3) - (6*5- 2) =

7 - (30 -2) =

7-28 = -21

b) (√4 +4) - (2√3-2)

(2+4) - (2√3-2)

6 - (3,46410162 -2)

6 - 1,46410162 = 4,53589838 ≈ 4,536

c) √16(√2 +1) - (√5-3)

4(√2 +1) - (√5-3) =

4 (1,41421356 + 1 ) - (- 0,763932) =

(5,65685425 + 4) - (- 0,763932) =

9,65685425 + 0,763932 = 10,4207863 ≈ 10,421

d) 2√5 (3 + √5 + 4√3)

2 * 2,23606798 (3 + 2,23606798 + 4*1,73205081) =

4,47213596 ( 3 + 2,23606798 + 6,92820324) =

4,47213596*(12,1642712) =

54,4002747 ≈ 54,4003

e) √3(√7 + 7 + √2)

1,73205081( 2,64575131 + 7 + 1,41421356)

1,73205081*(11,0599649) =

19,1564212 ≈ 19,16
