a. 1.9*10^-4, 1.7*10^-4, 1.4*10^-3, 1.2*10^-5
b. 1.2*10^-5, 1.7*10^-4, 1.9*10^-4, 1.4*10^-3
c. 1.9*10^-4, 1.7*10^-4, 1.2*10^-5, 1.4*10^-3
d. 1.2*10^-5, 1.4*10^-3, 1.9*10^-4, 1.7*10^-4

a. 4^13
b. -4
c. 13
d. 1

Answer 1

10 ^-4 is .0010 just move to the left the amount it tells you and then multiple this is really simple. Good Luck
