Scientific notation<span> is the way that scientists easily handle very large numbers or very small numbers.

For example, instead of writing 0.0000000056, we write </span> $5.6 * 10^{-9}$ .

Hence, in scientific notation

0.000028 = $2.8 * 10^{-5}$

So, the answer is -5. The power of ten has to be -5.

-5 as that you would have to count that places to the left. You end decimal would have to be between 1 and 10, so it would not count the 8. I'm sorry if my explanation is not good, but that is the right answer

-9=-3(x+2)<br>solve for x <br>show steps

SimplifyOkie dokie so first things first, you have to get rid of those parentheses! To do this you use the distributive property. -3(x+2) is the same thing as -3(x)+-3(2). that and you get -9=-3x-6. So you want to get x by itself to be able to find what x is, so you add 6 to both sides of the equation to get rid of the -6. So then you get -3=-3x. Then you must divide both sides by the coefficient of x, which would be -3. When you divide both sides by -3 you get -3/-3=x, which is the same thing as 1=x. Hope this helped!
