Question

3 mũ 2 . {450 : [200-(17 +23) mũ 5 : 50 mũ 4]}

Answer 1

Tính nhanh nếu có thể

Answer 2

\(3^2.\left\{450:\left[200-\left(17+23\right)^5:50^4\right]\right\}\)

\(=3^2.\left\{450-\left[200-50^5:50^4\right]\right\}\)

\(=3^2.\left\{450-\left[200-50\right]\right\}\)

\(=3^2.\left\{450-150\right\}\)

\(=9.300\)

\(=2700\)

Answer 3

Chú giải 3 mũ 2 = 3^2 thay mũ = dấu ^ này nhé
->=3^2{450:[200-40^5:6250000]}
=3^2{450:[200-102400000:6250000}  
=3^2{450:[200-16,384]}
=3^2{450:183.616}
=3^2{450:183.616}
=9.2
=18
