Answer 1

Its equivalence of numbers according to notations

Then we see all options can be rewrited to the form

125 x 10 ^ Power

But theres only one correct choice

125 x 10^6

then first option a) gives

125 x (10^ -2)• (10^6) = 125 x 10^4

option b)

125 million = 125 x 10^6

option c)

125 x (10^6)•(10^-2) = 125 x 10^4

option d)

125 x (10^3)• (10^6) = 125 x 10^9

option e)

125 x (10^-3) • (10^6) = 125 x 10^3

THEN we see theres only one option that fits the result searched.

Its option b) 125x 10^6
