Step-by-step explanation:

can also be written as 2i
where i = √-1

Rationalizing denominator,
Answer:
x ≅ 20.10 torr
Step-by-step explanation:
Given that the equation which models blood pH in the question is;
pH(x)=6.1+log(800/x)
where;
pH = 7.7
x = partial pressure of carbon dioxide in arterial blood, measured in torr.
we are asked to find (x)
In order to do that, we use the given equation:
pH(x)=6.1+log(800/x)
since pH = 7.7
7.7 = 6.1 + log (800/x)
7.7 - 6.1 = log (800/x)
1.6 = log (800/x)


x = 20.09509145
x ≅ 20.10 torr
