Question

7. what is the solution to (3×10^2)x(5×10^5) written in scientific notation? (1 point)

a-1.5x10^8
b-15x10^8**
c-1.5x10^7
d-15x10^7

HELP PLS
the commutative property says that
(3×10^2)x(5×10^5) = (3*5)×(10^2 * 10^5) = 15×10^7
but that is not yet quite scientific notation. A is the right choice.
