Scientific notation for googleplex?
It is 1*10googol = or 1*1010100. It is not easy to illustrate the two levels of superscript so I have put the base in subscript, etc.
How do you divide and multiply in scientific notation?
Suppose p = a*10^x and
q = b*10^y are two numbers in scientific notation.
Then p*q = (a*b)*10^(x+y)
where, 1 <= |a|,|b| < 10 implies that 1 <= |a*b| < 100.
If a*b is greater than or equal to 10, let a*b = 10*c
then in scientific notation, p*q = c*10^(x+y+1).
Also p/q = (a/b)*10^(x-y)
where, 1 <= |a|,|b| < 10 implies that 0 < |a/b| <= 1.
If a/b is less than 1, let a/b = c/10
then in scientific notation, p/q = c*10^(x-y-1).
What is the scientific notation for 0.025?
Move 2 decimal places to the right, so the exponent for base 10 is -2. Therefore, 0.025 in Scientific Notation is 2.5 x 10-2
