Step-by-step explanation:
Multiply the numbers 7.36 and 4.9 together
7.36 x 4.9 = 36.064
Then multiply 10^3 by 10^5
If you go back to the indices laws, 10^3 x 10^5 = 10^3+5 = 10^8 as you add the indices together when multiplying
Now add them together: 36.064 x 10^8
But, in scientific notation, the number at the front must be between 1 and 10 so divide 36.064 by 10 to get 3.6064 which is over 1 but below 10.
This adds to the amount of times you multiply by 10 so 10^8 becomes 10^9
Final answer = 3.6064 x 10^9
