e)√25+√1-³√8​

Answer 1

Resposta:

A)-94

B)90

C)43243467

D)12

E)3,18

Explicação passo-a-passo:

A) (-8²)+2.√36-42

=-64+2.6-42

=-64+12-42

=-52-42

=-94

B) √144-2.(8+2²:4)

=12-2.(8+4:4)

=10.(8+1)

=10.9

=90

C) -76+(8+7³)³-√64

=-76+(8+343)³-8

=-76+(351)³-8

=-76+43243551-8

=43243467

D)√16+√64

=4+8

=12

E)√25+1-³√8

=5+1-2,82

=6-2,82

=3,18
