Mathematical Constants
Intriguing, ubiquitous, and at times mysterious, numerical constants set the allowable limits for all universal phenomena. Whether your questions involves π, Avogadro's number, Planck's constant, the atomic mass unit, or any of the other multitudes of immutable numbers used in science, this is the category where they should be asked.

How many zeros are at the end of the number googol?
A googol is 1 followed by one hundred 0s.
A googol is 1 followed by one hundred 0s.
A googol is 1 followed by one hundred 0s.
A googol is 1 followed by one hundred 0s.
What is this amount 9 000 000 000 000 000 000?
This number has a 9 followed by 18 zeroes. We can write this in standard form as 9 x 1018.
1 x 1018 is equal to a quintillion.
Therefore this number is nine times as large and is 9 quintillion.
(Note: This answer is using the American & seemingly modern British definition of a quintillion rather than the traditional British system).
See Gabriel Lame (1795-1870). Also see Stress-Strain Relationships, Bulk Modulus, and Theory of Elasticity.
What is the definiton of constant?
CONSTANT - fixed: unchangeable: firm: continual: faithful. In maths it means a fixed quantity.
What is the base unit of Plancks constant?
Planck's constant relates the energy level of radiation due to electrons moving from one energy level to another, by the formula Energy = (Planck's constant) x (frequency of radiation). Therefore the dimensions of Planck's constant are (energy)/(frequency) which means Joules x seconds
In fact Planck's constant = 6.67 x 10-34 joule.seconds.
Why can't a number be divided by 0?
If you allow division by zero it leads to results which are indeterminate or even nonsensical.
A proof that 1 = 2 always relies on a division by zero cunningly hidden in the algebra.
What are the first 300 decimals of pi?

Broken into chunks of 50.
If you wanted to know these for memorisation, there are thousands of results from searching "digits of pi", some of which can display up to the first million digits.
What do you need to line up decimal points before comparing and ordering numbers with decimals?
You do not, but it is easier.
What are the dimensions of Stefen Boltzmann constant?
The dimensions are [L^2MT^(-2)K^(-1)]
where
L = length
M = Mass
T = Time
K = Temperature
The square root of two is an irrational number that when multiplied by itself gives you the value 2. It is approximately equal to 1.4142135623730951.
Different kinds of energy waves that move at the speed of light in a vacuum make up the?
In any substance, all electromagnetic waves travel at the same speed
that light travels through that substance.
What is four times the difference of x and seven times x?
Let's start with the problem: 4(x-7x)
The first step that needs to occur is distribution, also known as distributing. Distributing involves multiplying the number on the outside of the parenthesis by each of the numbers inside of the parenthesis.
In this case, you would multiply 4 and x, as well as 4 and -7x.
You end up with 4x-28x, and when you subtract 28x from 4x, you get -24x as your final answer.
