Question

100: {250 : [ 450 - ( 4.5³ - 2² . 25 ) ] }

Đề : thực hiện phép tính             giúp mình với cảm ơn nha

Answer 1

\(100:\left\{250:\left[450-\left(4.5^3-2^5.25\right)\right]\right\}\)

\(=100:\left\{250:\left[450-\left(500-800\right)\right]\right\}\)

\(=100:\left\{250:\left[450+300\right]\right\}\)

\(=100:\left\{250:700\right\}\)

\(=100:\frac{5}{14}\)

\(=280\)

Answer 2

100:{250:[450 - ( 4 . 125 - 4.25 )]}

100: { 250: [  450 - ( 500 - 100 ) ]}

100: {250:[ 450 - 400]

100: { 250 : 50 }

100: 5 = 20
