f)2 √81 + 3√144/ 2√64 - 3 ∛27 - ∛1

Answer 1

Explicação passo-a-passo:

a)√9 + 5√3 - 3 ⁴√16=

=3 + 5√3 - 3 × 2=

=3 + 5√3 - 6=

=-3 + 5√3

b)5√4 · 2∛343 ÷ 1 ⁴√10000=

=5 × 2 - 2 × 7 × 10=

=10 - 140=

=-130

c)3√16 - 2 ∛27 + 3 ⁴√81=

=3 × 4 - 2 × 3 + 3 × 3=

=12 - 6 + 9=

=15

d)7√4 - 2 ∛8 + 1 ⁴√1=

=7 × 2 - 2 × 2 + 1 ×1=

=14 - 4 + 1=

=9

e)√√1296/16 + √256/4=

=√√81 + √64=

=√9 + 8=

=3 + 8=

=11

f)2 √81 + 3√144/ 2√64 - 3 ∛27 - ∛1=

=2 × 9 + 3√144/2 × 8 - 3 × 3 - 1=

=18 + 3√144/16 - 9 - 1=

=18 + 3√9 - 8=

=18 + 3 × 3 - 8=

=18 + 9 - 8=

=19
