Answer:

Explanation:

5 x 10^3 x 9 x 10^7 can be written as follows in standard form:

5 x 10^3 = 5 x 10^3 x 1 = 5 x 10^3

9 x 10^7 = 9 x 10^7 x 1 = 9 x 10^7

So,

5 x 10^3 x 9 x 10^7 = (5 x 10^3) x (9 x 10^7) = 45 x 10^(3 + 7) = 45 x 10^10 = 4.5 x 10^11

In standard form, the coefficient (45) is written as a number between 1 and 10, and the exponent (10) gives the number of places the decimal point must be moved. So, 4.5 x 10^11 is written in standard form as 4.5 x 10^11.
