Answer 1

in Scientific Notation, a number has to be between 1 and 10.
so all you would have to do is move the decimal place either to the left or right as many times as it takes to be a number from 1-10.

#1) 10,000 =1 x 10^4
(this is because the decimal got moved over 4 places to the left, therefore when you multiply 10^4, you get your original number of 10,000.
in other words, once you move the decimal over 4 spaces to the right [positive], you end up with 10,000.)

#2)0.0001 = 1 x 10^-4

#3) 10,000,000,000= 1 x 10^10

#4) 50,000 = 5 x 10^4

...

Answer 2

1) 1 x 10^4
2) 1 x 10^-4
3) 1 x 10^11
4) 5 x 10^4
5) 2 x 10^9
6) 2 x 10^-6
You get the idea.

Answer 3

Easy way to remember: when you count from right to left, your answer should be raised to the positive. Counting from left to right should be raised to a negative.

1)1x 10^4 because count is from right to left
2)1x 10^-4 " " "' from left to right
3)1x 10^10
4)5x10^4
Apply the above concepts to help you figure out the rest of the problems.

Hope this helps.
