When we simplify this problem, we are rationalizing the denominator.

Now, let's solve this problem:

First thing, we multiply the expression by sqrt(7)/sqrt(7)77. We can do this because sqrt(7)/sqrt(7)77 is simply 1, and multiplying something by 1 doesn't change the nature of the expression.

So, our expression is this: sqrt(67)/sqrt(7) * sqrt(7)/sqrt(7)67777

Multiplying, we get: sqrt(469)/sqrt(49)46949

Since sqrt(49)49 simplifies to 7, we get: sqrt(469)/74697

Since, sqrt(469)469 is not something we can simplify, our final answer is: sqrt(469)/74697

In a calculator, the answer is 3.093772546823.09377254682

If by simply, you mean to rationalize the denominator, multiple both the numerator and the denominator by sqrt(7)7:

(sqrt(67)/sqrt(7)) = ((sqrt(67) * sqrt(7)) / 7) = sqrt(469)/7(677)=(6777)=4697
