Function to grab specific digits from a number?
Recently I’ve been thinking a lot about grabbing digits from numbers, for things like calculating multiplication persistence, i.e. turning into a . I’ve been able to come up with
to output the number of digits of the given number x, as well as
which outputs the first n digits of any number x. But that’s about as far as I’ve been able to think up. Is there any way to construct a function that retrieves the nth digit of a given number? Forgive me if my notation or comprehension is poor, I have no formal education in this field of maths.
A cone has a height of 6 yards and a radius of 3 yards. What is its volume?
Use 𝜋 ≈ 3.14 and round your answer to the nearest hundredth.
a family has three children find the values of the random variable x representing the number of girls and construct a probability distribution
Find the equation of quadratic function given that the zeros are -3/4 and 5/6.
Logarithm rules, which one has priority?
Here are the two results I came up with:
I am sort of leaning towards the first result I got but I am not really sure. Could someone explain whether or not it is correct? I have looked at the log rules but I cannot recall which ones have priority over others.
