A scientist estimates that there are about 10^24 stars in the universe and that each galaxy has, on average, approximately the same number of stars as the Milky Way galaxy.
About how many galaxies are in the universe?
Milky Way galaxy: 10 • 10^10 stars

100'000'000'000'000

(trillion gaxies in the universe)

Step-by-step explanation:

10×10^10= 10(10'000'000'000)=100'000'000'000

(hundred billion stars in milky way)

100'000'000'000'000'000'000'000 (hundred sextillion stars in universe)

100'000'000'000'000'000'000'000 / 100'000'000'000= 100'000'000'000'000

(trillion gaxies in the universe)

answer: the first graph

step-by-step explanation:

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
