HOW DO YOU WRITE NUMBERS IN SCIENTIFIC NOTATION?
Hello, blame_canada100!
First of all, release your CapsLock.
All upper-case letters is impolite . . . it's shouting.
How do you write numbers in scientific notation?
A quantity in scientific notation is a number $\displaystyle n,\;1 \leq n < 10,$ times a power of 10.
Examples
. . $\displaystyle (a)\;238,000 = 2.38 \times 10^5$
. . $\displaystyle (b)\;0.00057 \,= \,5.7 \times 10^{-4}$
In example (a), $\displaystyle 238,000$ was transformed to $\displaystyle 2.38$
. . by moving the decimal point (far right) five places to the left.
In effect, we have divided by $\displaystyle 100,000$
. . so we multiply by $\displaystyle 100,000 = 10^5$
In example (b), $\displaystyle 0.00057$ was transformed to $\displaystyle 5.7$
. . by moving the decimal point four places to the right.
In effect, we have multiplied by $\displaystyle 10,000$
. . so we divide by $\displaystyle 10,000$ ... or multiply by $\displaystyle \frac{1}{10,000} = 10^{-4}$
