Question

\(10^2-\left[60:\left(5^6:5^4-3.5\right)\right]\)

Answer 1

\(=100-\left[60:\left[5^2-15\right]\right]=100-\left[60:\left[25-15\right]\right]\)

\(=100-\left[60:10\right]=100-6=94\)

Answer 2

\(=100-\left[60:\left(5.5-3.5\right)\right]\)

\(=100-\left\{60:\left[5.\left(5-3\right)\right]\right\}\)

\(=100-\left[60:\left(5.2\right)\right]\)

\(=100-\left(60:10\right)\)

\(=100-6=104\)

Chúc cậu thành công :D
