b) 13²-[4²+√9.(10²-8²) +(25-√144÷3)÷ (√16+3¹)=​

Answer 1

Resposta:

13² - [4² + √9.(10² - 8²) + (25 -√144 ÷ 3) ÷ (√16 + 3¹)

13² - [4² + √9 . (100 - 64) + (25 - 12 ÷ 3) ÷ (4 + 3)]

13² - [16 + √9 . 36 + (25 - 4) ÷ (4 + 3)]

13² - [16 + √9 . 36 + 21 ÷ 7]

13² - [16 + 3 . 36 + 3]

13² - [16 + 108 + 3]

13² - [124 + 3]

13² - 127

169 - 127

Answer 2

Resposta:

13² = 169

4² = 16

√9 = 3

10² = 100

8² = 64

√144 = 12

√16 =4

3¹ = 3

13²- [4² + √9.(10² - 8²) + (25 - √144 ÷ 3) ÷ (√16 + 3¹)]

169 - [16 + 3.(100 - 64) + (25 - 12 : 3) : (4 + 3)]

169 - [16 + 3.(36) + (25 - 4) : 7]

169 - [16 + 108 + 21 : 7]

169 - [16 + 108 + 3]

169 - 127
