4.53*10-6 0.00000453 is in standard notation just move the decimal place over how ever many times the exponent is on the 10
3.92 × 105 written in standard notation is 392,000
As far as I am aware, standard notation is just the common form of the number, as opposed to "scientific notation" which saves a hell of a lot of zeros being written all over the place. Eg....you 0.7 million in standard notation is simply 700,000. But in scientific notation could be written as 7x105.
Scientific notation is written like this: (number) * 10(exponent)Scientific notation is written by moving the decimal point over until there is only one digit in front of it. The number of times you have to move the decimal over is the exponent you use.Example: 786,450,000.0 --> Move the decimal over 8 times = 7.8645Answer: 7.8645 * 108If the number is a decimal, you do the same thing, but write a negative exponent instead of a positive.Example: 0.0004687219 --> Move the decimal over 4 times = 4.697219Answer: 4.697219 * 10-4
how many times does 258 go into 1000
