Question

325 - 5 [ 4 mũ 3 - ( 27 - 5 mũ 2 ) x 1 mũ 18 ]

Answer 1

\(325-5\left[4^3-\left(27-5^2\right)\cdot1^{18}\right]\\ =325-5\left[64-\left(27-25\right)\cdot1\right]\\ =325-5\left(64-2\right)=325-5\cdot62=325-310=15\)

Answer 2

\(325-5\left[4^3-\left(27-5^2\right).1^{18}\right]\)

\(=325-5\left[64-\left(27-25\right).1\right]\)

\(=325-5\left[64-2.1\right]\)

\(=325-5.62\)

\(=325-124\)

\(=201\)
