Answer 2

If you instead want it in standard notation, then recall that the -4 exponent on the 10 means to move the decimal point 4 places to the left.

Read cliff's comment blanca :) You can let us know if you're still confused though.

Answer 5

Then you do want it in standard notation. Remember that moving the decimal point to the right multiplies by ten for each place you move it, and moving the decimal point to the left divides by ten for each place.
The exponent on the ten in scientific notation tells you how many spaces to move the decimal point and in which direction ( '-' for left, '+' or no sign at all for to the right).
