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

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)

I'm not sure if helped you

the answer is 13 cm

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
