Answer:
a. 8.5 x 10^(-7)
b. 3.186 x 10^(7)
Step-by-step explanation:
ok so standard form means to put the number in terms of a number from 1-10 times 10 to a power of something (10^7)
for a you have to move the decimal to the right 7 times to make the number between 1 and 10 and since you had to carry the decimal to the right, it's a negative 10 power
for b you habe to move the decimal to the left 7 times to make the number between 1 and 10 and since you had to carry the decimal to the left, it's a positive 10 power
