How do you write in standard form? - Answers

Scientific notation is a way of representing numbers, usually very large or very small, in the forma*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*10^40.00023004 becomes 2.3004*10^-4To 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
