Answer 1

Ta có: \(170\cdot2011^0-17\cdot\left[83-1702:23+1^{2012}\right]+2^7:2^4\)

\(=170-17\cdot\left(83-74+1\right)+8\)

\(=178-17\cdot10=8\)

Answer 2

g: Ta có: \(100:\left\{250:\left[450-\left(4\cdot5^3-2^3\cdot25\right)\right]\right\}\)

\(=100:\left\{250:\left(450-300\right)\right\}\)

\(=100:\left(250:150\right)\)

\(=100:\dfrac{5}{3}=100\cdot\dfrac{3}{5}=60\)
