Question

CALCULE O VALOR DAS EXPRESSÕES:

Answer 1

4)
a)⁴√16 - ∛-1
      2 - ( - 1) = 2 + 1 = 3
b)₇√-1 - √16 - ∛27 = 
     -1 - 4 - 3 = -8
c)√8²+6²  . ∛2³ - 3²
√64+36 . ∛8-9
√100 . ∛-1 = 10 . - 1 = -10
d)2√25 -√144 = 2 . 5 - 12 = 10 - 12 = -2
e)-∛64 + ⁴√16 = -4 + 2 = -2
f)-2³ +3⁴ - 10² = -8+81-100 = -27
g)√36 +7° + (-5)² = 6 + 1 + 25 = 32
h)-10³ + 10² - (-4)² = -1000 + 100 - (+16) = -1000 + 100 - 16 = -916
i)2⁵ + 2 ⁴ + 2³ + 2² + 2¹ + 2° = 
  32 + 16 + 8 + 4 + 2 + 1 = 63
j)-7³ + 6³ - 5³ = -343 + 216 - 125 = -252
