Question

Simplify: 3 (2³ − 4 + 11) - 5² (6² - 3 + 12)​

Answer 1

Answer:

-1080

Step-by-step explanation:

3(8-4+11)-25(36-3+12)

3(19-4)-25(48-3)

2(15)-25(45)

45-1125

-1080

Answer 2

Answer:

3(2^3-4+11)-5^2(6^2-3+12)

=3(8-4+11)-25(36-3+12)

=3(19-4)-25(48-3)

=3×15-25×45

=45-25×45

=45(1-25)

=45× -24

= -1080
