Simplify the expression. Write the answer using scientific notation. (9 x 10^5) (3 x10^10)

Answer:
Should be 2.7 x 10^16
Step-by-step explanation:
(9 x 10^5) (3 x10^10)
Multiply 9 by 3
9 x 3 = 27
Add the exponents
10^5 + 10^10
Results in
27 x 10^15
However that isn't an answer choice. But 2.7 x 10^16 is the same as 27 x 10^15
Answer:
(x^10)(x^2) Add the exponents 10+2=12 So... (x^12)
