Answer 1

Resposta:

10) 1

11) 12√5 cm

12) 18 cm

13) 7√6 - 12√19/19

Explicação passo-a-passo:

10)

= (3√3 + 5√3 + √48) ÷ 6√12

= (3√3 + 5√3 + √2⁴ × 3) ÷ (6√2² × 3)

= (3√3 + 5√3 + 2²√3) ÷ (6 × 2√3)

= (3√3 + 5√3 + 4√3) ÷ 12√3

= 12√3 ÷ 12√3

= 1

11)

P = 3√5 + √80 + √125

P = 3√5 + √(2⁴ × 5) + √(5² × 5)

P = 3√5 + 2²√5 + 5√5

P = 3√5 + 4√5 + 5√5

P = 12√5

12)

A = (√12) × (√27)

A = (√2² × 3) × (√3² × 3)

A = (2√3) × (3√3)

A = 6(√3)²

A = 6 × 3

A = 18

13)

= √3 × (√18 + √32) - √144 ÷ √19

= √3 × (√3² × 2 + √2⁴ × 2) - √12² ÷ √19

= √3 × (3√2 + 4√2) - 12 ÷ √19

= √3 × 7√2 - 12 ÷ √19

= 7√6 - 12√19/19
