what is the simplified form of (3.25 times 10^3)(7.8 times 10^6) written in scientific notation?

Question

2.535 times 10^10
2.535 times 10^18
2.535 times 10^19
25.35 times 10^9

Answer 1

To simplify (3.25 times 10^3)(7.8 times 10^6) in scientific notation, we use the product of the two numbers and add the exponents:

(3.25)(7.8) = 25.35

(10^3)(10^6) = 10^(3+6) = 10^9

Therefore, the simplified form is 25.35 times 10^9.
