Question

80 - ( 4.5 mũ 2 - 3 . 2 mũ 3)

Answer 1

    80 - ( 4 . 5² -3  . 2³ )
→ 80 - ( 4 . 25 - 3 . 8 )
→ 80 - 76
→ 4

Answer 2

= \(80-\left(4,5^2-3.2^3\right)\)

= \(80-\left(20,25-3.8\right)\)

= \(80-\left(20,25-24\right)\)

= \(80-\left(-3,75\right)\)

= \(83,75\)

Answer 3

Answer 4

80 − ( 4.\(5^2\)− 3.\(2^3\) )

= 80 − ( 4.25 − 3.8 )

= 80 − ( 100 − 24 )

= 80 − 100 + 24

= − 20 + 24

= 4
