The answer would be 20000
The answer in standard form/scientific notation would be 2 x 10^4
(The exponent is 4 because that's how many digits after the 2 there is)
I agree with the first responses

Complete Question
The complete question is shown on the first uploaded image
Answer:
The total pressure is 
The temperature at the bottom is 
Explanation:
From the question we are told that
The length of the glass tube is 
The length of water rise at the bottom of the lake 
The depth of the lake is 
The air temperature is 
The atmospheric pressure is 
The density of water is 
The total pressure at the bottom of the lake is mathematically represented as

substituting values


According to ideal gas law
At the surface the glass tube not covered by water at surface

Where is the volume of

At the bottom of the lake

Where
is the volume of the glass tube not covered by water at bottom
and
i the temperature at the bottom
So the ratio between the temperature at the surface to the temperature at the bottom is mathematically represented as

substituting values

=>
