How To get rid of radicals in the denominator by multiplying the fraction by a helpful form of?
If there is only the radical, sqrt(b), in the denominator, the form of the fraction is sqrt(b)/sqrt(b).If the denominator is of the form a + sqrt(b) then the form of the fraction is [a - sqrt(b)]/[a - sqrt(b)].It is also possible to use [-a + sqrt(b)]/[-a + sqrt(b)], and this form may be preferred is a^2 < b.
Is it possible to make a physical measurement obtain an irrational number?
Yes; there are some lengths that can be measured but not described by the form a/b, where a and b are integers. For example, a right triangle with legs of length 1 has a hypotenuse of the square root of 2, which is an irrational number.
How do you write the point-slope form of an equation of the line described?
No line described, but here is the point slope form. Y - Y1 = m(X - X1) =============
What does or mean in probibility?
"or" is used in the context of sets [of events] rather than probability (and certainly not probibility!),An event described as A or B means either event A or event B or both events."or" is used in the context of sets [of events] rather than probability (and certainly not probibility!),An event described as A or B means either event A or event B or both events."or" is used in the context of sets [of events] rather than probability (and certainly not probibility!),An event described as A or B means either event A or event B or both events."or" is used in the context of sets [of events] rather than probability (and certainly not probibility!),An event described as A or B means either event A or event B or both events.
What is a logarithem?
You mean a logarithm... It can be described as this: a log b = x --> a^x = b So it's a way of discovering the power 'x' that the variable 'a' needs to be 'b'
