Question

In standard form when do we put a negative power and a positive one

Answer 1

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)

I'm not sure if helped you
