Question

DETERMINE O VALOR DAS EXPRESSÕES
A-) √9+√36-√49=


B-) ∛8+∛100-∛1000=
------------------------
√4

C-) 3.√16-10√64+√2500=


D-)∛64+4√25-2∛8=
-----------------------
√400

Answer 1

A-
√9+√36-√49=
=3+6-7
=2
B-
∛8+∛100-∛1000=
=2+4.7+10
=16.7x10
C-
3.√16-10√64+√2500=
=3 x 4 -(10x8)+50
=12-80+50
=12-30
=-18
D-
∛64+4√25-2∛8=
=4+4x5-2x2
=8 x 5 - 4
=40-4
=36
E-
√400
=20
