a,5^x+1=125

Answer 1

125=5³

=>x+1=3

=>x=2

Answer 2

5^{x + 1} = 125

<=> 5^x . 5 = 125

<=> 5^x = 25

<=> x = 2

hoặc:  5^{x + 1} = 125

<=> x + 1 = 3

<=> x = 2

Answer 3

5^x+1 = 125

5^x+1= 5³

=> x + 1 = 3

x = 3 - 1

x = 2

vậy x = 2

Answer 4

Ta thấy rằng : \(125=5^3\)

\(=>5^{x+1}=125\)

\(=>x+1=3\)

\(\Leftrightarrow5^{x+1}=5^3\)

\(\Rightarrow x+1=3\)

\(\Rightarrow x=3-1\)

\(\Rightarrow x=2\)

Answer 10

ta có: 125= 5^x+1
