Question

Thực hiện phép tính :

100:{250:[450-(4.5³-2².25)]}

Answer 1

  100:{250:[450-(4.5^3-2^2.25)]}

=100:{250:[450-(4.125-4.25)]}

=100:{250:[450-(500-100)]}

=100:{250:[450-400]}

=100:{250:50}

=100:5

=20

Answer 2

\(100:\left\{250:\left[450-\left(4.5^3-2^2.25\right)\right]\right\}\)

= \(100:\left\{250:\left[450-\left(2^2.5^3-2^2.5^2\right)\right]\right\}\)

= \(100:\left\{250:\left[450-2^2.5^2\left(5-1\right)\right]\right\}\)

= \(100:\left[250:\left(450-100.4\right)\right]\)

=\(100:\left(250:50\right)\)

= \(100:5\)

= \(20\)
