Scientific Notation Excitement!
Are you ready to dive into the world of scientific notation?
Let's test your knowledge with the following question:
The result of multiplying 7.5 x 10^4 by 2 x 10^3 is:
a. 1.5 x 10^8.
b. 1.5 x 10^7.
c. 15 x 10^6.
d. 15 x 10^7.
Answer:
The correct answer is b. 1.5 x 10^7.
When multiplying numbers in scientific notation, you multiply the coefficients and add the exponents. In this case:
7.5 x 10^4 * 2 x 10^3 = 15 x 10^7 = 1.5 x 10^8
So, the answer is not a. or c. but b. 1.5 x 10^7.
