Answer 1

Resposta:

1) (19×7)²+(25×3)²-(30×2)² 2)

133² + 75² - 60² =

=17.689 + 5.625 - 3.600 =

=19.714

2) (1970-1830)+(7930-5740)

=140 + 2.190=

=2.330

3) (195+870)+(1977+3870)-(-7890-8753)

=1.065 + 5.847 + (-863) =

=6.912 - 863 =

= 6.049

4) (15×150)+(11×1)³-(12×2)²+(12×150)

=2.250 +  11 ³ - 24 ² + 1.650 =

= 2.250 + 1.331 - 576 + 1.650 =

=4.655
