Scientific Notation
Scientific notation is the expression of a number based on the largest exponent of 10 for its value, where the form is a decimal number A x 10n.

What are the two factors of scientific notation?
Not sure about "factors", but the two elements are the mantissa and the exponent.
Scientific notation is a way of representing numbers, usually very large or very small, in the form a*10^b where 1 <= |a| < 10 is a decimal number and b is an integer (negative or positive). a is called the mantissa and b is called the exponent.
How is a number converted to scientific notation?
Scientific notation is a way of representing numbers, usually very large or very small, in the form
a*10b where 1 ?|a| < 10 is a decimal number and b is an integer (negative or positive).
a is called the mantissa and b is called the exponent.

How do you calculate 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). Suppose you have two numbers in scientific notation.
· Rename them so that the exponents (powers of 10) are the same, · add the two mantissae to form the new mantissa, and append the 10 and exponent, · if the resulting mantissa is 10 or greater then rename the mantissa and adjust the exponent accordingly.
For the first stage you may rename both numbers or either one.
For example,
3.5*10^3+ 4.5*10^4= 3.5*10^3+ 45*10^3= (3.5+45)*10^3= 48.5*10^3= 4.85*10^4
or
3.5*10^3+ 4.5*10^4= 0.35*10^4+ 4.5*10^4= (0.35+4.5)*10^4= 4.85*10^4
Write the equivalent measurement?
Equivalent measurement are measurements of the same characteristic which are made using two different units. For example, 20 deg C and 68 deg F are equivalent measurements.
How do you write 0.53 in scientific notation?
0.53 written in scientific notation is 5.3 * 10^ -1 or 5.3E-1
