What is the product of 7.67x10^9 and 5.9x10^-6 expressed in scientific notation.
A.1.3x10^3
B.4.5253x10^3
C4.5253x10^4
To multiply these numbers in scientific notation, you multiply the coefficients and add the exponents:
(7.67)(5.9) = 45.253
(10^9)(10^-6) = 10^(9 - 6) = 10^3
So, the product of 7.67x10^9 and 5.9x10^-6 is 45.253x10^3, which can be expressed in scientific notation as 4.5253x10^4.
Therefore, the correct answer is option C.4.5253x10^4.
