Question

a) 4.3^4 - 16:2^2 + 2.5^3

b) 100 : {250:[450-(4.5^3 - 25.4)]}

nếu giải rõ 3 tick sẽ đến bên bạn

Answer 1

a) \(4.3^4-16:2^2+2.5^3\)

\(=4.81-16:4+2.125\)

\(=324-4+250\)

\(=570\)

b) \(100:\left\{250:\left[450-\left(4.5^3-25.4\right)\right]\right\}\)

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

\(=100:\left\{250:\left[450-400\right]\right\}\)

\(=100:\left\{250:50\right\}\)

\(=100:5\)

\(=20\)

nhớ là 3 k nhá

Answer 2

a) 4.3^4-16:2^2+2.5^3

= 4.81-16:4+2.125

= 324-4+250

= 320+250

= 570

b)100:{250:[450-(4.5^3-25.4)]}

= 100:{250:[450-(4.125-100)]}

= 100:{250:[450-(500-100)]}

= 100:{250:[450-400]}

= 100:{250:50}

= 100:5

= 20

nhớ đúng cho mình nha
