Question

(2)³ - 45 : (-3²) + (-2019)⁰ . (-1)²⁰¹⁹

=?

Answer 1

    \(2^3-45:\left(-3\right)^2+\left(-2019\right)^0\cdot\left(-1\right)^{2019}\)
\(=8-45:9+1\cdot\left(-1\right)\)
\(=8-5+\left(-1\right)\)
\(=3+\left(-1\right)\)
\(=2\)

Answer 2

(2)³ - 45 : (-3²) + (-2019)⁰ . (-1)²⁰¹⁹

= 8 - 45 : 9 + 1 . (-1)

= 8 - 5 + (-1)

= 3 + (-1)

= 2
