Question

(3 x 10^6) x (3 x 10^ 5)

Answer 1

`9*10^(11)`

Explanation:

we have

`(3*10^(6))*(3*10^(5))`

we know that

`(a*10^(b))*(a*10^(c))=(a*a)*10^((b+c))` -----> the bases are multiplied and the exponents are added up

so

in this problem

`(3*10^(6))*(3*10^(5))=(3*3)*10^((6+5))`

`=9*10^(11)`
