Answer:
Step-by-step explanation:
for negative power,you put it when you're counting backwards
for example,
writing standard form of 0.000 0012 will be
1.2 x 10^-6 (1.2 into ten to the power minus 6)
the decimal is going backwards in order to get 1.2 and it has skipped 6 digits/numbers in between.
for positive power,it is when you go forward
for example,
writing standard form of 8000 will be
8 x 10^3 (eight into ten to the power 3)
there is no decimal in 8000,so we move the decimal from the very last 0(zero)
