Giúp minh nha nhanh minh tíck

Answer 1

lộn

\(\left|\left(-3\right)^2-\left(-2\right)^3\right|:\left|4-\left(-2\right)^2+30^0\right|\)

\(=\left|9-\left(-8\right)\right|:\left|4-4+1\right|\)

\(=\left|9+8\right|:\left|1\right|\)

\(=\left|17\right|:1\)

\(=17:1\)

\(=17\)

Answer 2

\(\left[\left(-3\right)^2-\left(-2\right)^3\right]:\left[4-\left(-2\right)^2+30^0\right]\)

\(=\left[9-\left(-8\right)\right]:\left(4-4+1\right)\)

\(=\left(9+8\right):1\)

\(=17:1\)

\(=17\)
