Bài 1 câu e đi ạ mai đi hoc rồi🥲giải đc fl

Answer 1

1) 

e) \(500-3\cdot\left\{3^3+5\cdot\left[2^3\cdot3-19\cdot\left(2^2\cdot3-11\right)\right]\right\}\)

\(=500-3\cdot\left\{27+5\cdot\left[8\cdot3-19\cdot\left(12-11\right)\right]\right\}\)

\(=500-3\cdot\left[27+5\cdot\left(24-19\right)\right]\)

\(=500-3\cdot\left(27+5\cdot5\right)\)

\(=500-3\cdot52\)

\(=500-156\)

`=344`

Answer 2

Bài 2: 

a: =>x+37=50

=>x=13

b: =>40+(x+5)=45

=>x+5=5

=>x=0

c: =>x=23+17=40

d: =>2x-1=5

=>2x=6

=>x=3

e: =>\(3\cdot2^x=3^2+15=24\)

=>2^x=8

=>x=3

f: \(\Leftrightarrow5\cdot x^3=19+21=40\)

=>x^3=8

=>x=2

g: =>5x=5^4

=>x=5^3=125
