Cứu e vs :<

Thực hiện phép tính

a) 58.57 + 58.150 – 58.125                         b) 3².5 - 2².7 + 83.2019⁰

c) 2019 + (-247) + (-53) – 2019                  d) 13.70 – 50 [(19 - 3²) : 2 + 2³]

Answer 1

a: =58(57+150-125)=58x82=4756

b: \(=9\cdot5-4\cdot7+83=45-28+83=100\)

c: =(2019-2019)+(-247-53)=-300

d: \(=13\cdot70-50\cdot\left[10:2+8\right]=910-50\cdot13=910-650=260\)

Answer 2

\(a,=58.\left(57+150-125\right)\\ =58.82=4756\\ b,=9.5-4.7+83.1\\ =45-28+83=100\)

Answer 3

\(a.4756\\ b.100\\ c.-300\\ d.260\)
