Question

100 : { 250 [ 450 - ( 4.5^3 - 2^2 .25) ]} = ??

Answer 1

\(=100:\left\{250\left[450-\left(4\cdot125-4\cdot25\right)\right]\right\}\\ =100:\left[250\left(450-400\right)\right]\\ =100:\left(250\cdot50\right)=100:12500=12,5\)

Answer 2

100 : { 250 [ 450 - ( 4.5^3 - 2^2 .25) ]} = 12,5

Answer 3

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

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

=100:{250:50}

=100:5

=20
