Scientific notation is a way of representing numbers, usually very large or very small, in the form
a*10^bwhere 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.
To convert a number to scientific notation:
· If the number has no decimal point, then add one at the end.
· Then move the decimal point to just after the first digit while counting the number of places you have moved it.
· The mantissa of the new number, formed after moving the decimal point is a.
· If the original number is negative, then so is a.
· The number of places to the left that the decimal point was moved is b. If it was moved to the right, then b is negative.
For example:
23045.06 becomes 2.304506*10^4
-23045.06 becomes -2.304506*10^4
0.00023004 becomes 2.3004*10^-4
To convert a number in scientific notation to normal form:
· If b is positive, move the decimal point b places to the right in the number a - adding 0s at the end of the number, if required.
· If b is negative, move the decimal point b places to the left in the number a - adding 0s immediately after the decimal point, if required.
· The final expression has the same sign (+ or -) as a in the scientific form.
For example:
4.56*10^5 = 456000.
-4.56*10^5 = -456000.
4.56*10^-5 = 0.0000456
That IS the standard form.
You write 20.7 in standard form as: 2.07 × 101
9+800 is how you write it in standard form
Standard form simply means to write the number: 3,000,296,556

It is already in standard form.
That is the standard form.
That is the standard form!
That IS the standard form.
