Answer 1

10. To transfer a number into scientific notation, we must make sure that only one sig fig is to the left of the decimal. Therefore we can find that 0.00005 L = 5x10^-5 L

16. Given that a square is equivalent on all four sides, we divide 900 by 4 to find the length of each side. Thus, 900/4=225cm
