Multiply (2.0 ⋅ 10-4) ⋅ (3.1 ⋅ 10-20). Express the answer in scientific notation. 6.2 ⋅ 10-80 6.2 ⋅ 10-24 6.2 ⋅ 1024 6.2 ⋅ 1080

Scientifice notation is

(number less than 10 but greater than or equal to 1) times (10^x)

remember

(ab) (cd) = abcd = (ac) (bd)

and

(x^m) (x^n) = x^ (m+n)

so

(2*10^4) (3.1*10^20) =

(2) (10^4) (3.1) (10^20) =

(2*3.1) (10^4*10^20)

(10^4) (10^20) = 10^ (4+20) = 10^ (24)

(6.2) (10^24)

scientifie notiaotn is

6.2*10^24
