Question

Determine o valor das expressoes
A)-√81-³√-27=
B)³√0+³√-1+√0,25=
C)⁴√0,0001=

Answer 1

Resposta:

A)

$- \sqrt{81} - \sqrt[3]{ - 27} = \\ - 9 - ( - 3) = \\ - 9 + 3 = - 6$

B)

$\sqrt[3]{0} + \sqrt[3]{ - 1} + \sqrt{0.25} = \\ 0 + ( - 1) + 0.5 = \\ ( - 1) + 0.5 = - 0.5$

C)

$\sqrt[4]{0.0001} = 0.1$
