Final answer:
The product of 700 and 300 will have 5 zeros.
Step-by-step explanation:
If you multiply 700 and 300, you will get 210,000. In scientific notation, this number can be written as 2.1 x 10^5. To determine the number of zeros in the product, you look at the exponent of 10. In this case, the exponent is 5, which means there will be 5 zeros in the product. Therefore, the product of 700 and 300 will have 5 zeros.
