Question

\(e,2.5^{x+1}=50\)

Answer 1

\(2.5^{x+1}=50\\ =>5^{x+1}=\dfrac{50}{2}=25=5^2\\ =>x+1=2\\ =>x=1\)

Answer 2

\(2.5^{x+1}=50\Rightarrow5^{x+1}=5^2\Rightarrow x+1=2\) \(\Rightarrow x=1\)

Answer 3

e, 2 . 5^x+1 = 50

5^x+1 = 50 : 2

5^x+1 = 25

5^x+1 = 5²

=> x = 2 - 1

=> x = 1.

Answer 4

`2 . 5^(x +1) = 50`

`<=>` 5^(x + 1) = 25`

`<=> 5^(x + 1) = 5^2`

`<=> x + 1 =2`

`<=> x      = 1`

Answer 5

2.5x+1=50

=>5x+1=50:2=25=5^2

=>x+1=2

=>x=1
