Question

2(x -51 ) = 2.2^3 + 20

Answer 1

\(2\left(x-51\right)=2.2^3+20\)

\(\Leftrightarrow2\left(x-51\right)=16+20\)

\(\Leftrightarrow2\left(x-51\right)=36\)

\(\Leftrightarrow x-51=13\)

\(\Leftrightarrow x=64\)

Vậy ..

Answer 2

cho mk hỏi xíu 2,2\(^3\) + 20 hay là 2\(\times\)2\(^3\)+20 vậy

Answer 3

2(x-51)=2.2³+20

2(x-51)=2⁴+20

x-51=36:2

x=18+51

x=69

Answer 4

2(x-51) = 2.2\(^3\) + 20

2(x-51) = \(2^4\) + 20

2(x-51) = 16 + 20

2(x-51) = 36

x-51 = 36:2

x-51 =13

x = 13+51

x = 64

vậy x = 64

Answer 5

2(x-51)=2.2³+20

2(x-51)=2⁴+20

2(x-51)=16+20

2(x-51)=36

x-51=36:2

x-51=18

x=18+51

x=69
