Final answer:
To find the product of 2.8x10³ and 9.7x10³ expressed in scientific notation, you multiply the two numbers and add the exponents.
Step-by-step explanation:
To find the product of 2.8x10³ and 9.7x10³ expressed in scientific notation, you multiply the two numbers and add the exponents. In this case, the product of 2.8 and 9.7 is 27.16.
The exponents, 10³ and 10³, can be added to give 10²⁺³ = 10⁵.
Therefore, the product of 2.8x10³ and 9.7x10³ expressed in scientific notation is 27.16x10⁵.
