the answer should be 2x10^4 why cus you have to divide 12/6 is 2 x 10 and 9-5 is 4 for the exponents. so it goes out like this 2x10^4 . hope I helped of not then iam sorry.
First, find the exponents in each parenthesis. 10 to the power of 9 is 1,000,000,000. 10 to the power of 5 is 100,000. 1 billion X 12 is 12 billion. 6 times 100 million is 600 million. Then divide. Cross out the 0s and it'll give you 12,000 divided by 6. Which is 2,000. The answer is 2,000.
To solve ( 12 × 1 0 9 ) ÷ ( 6 × 1 0 5 ) , divide the coefficients giving you 2, and subtract the exponents resulting in 1 0 4 . Thus, the answer is 2 × 1 0 4 .
