When a whole number is multiplied by one to the 10th power (which is 1), the product is that number itself. Multiplying by 1 does not change the value of the original number.
However, if you meant multiplying a whole number by 10 raised to the 10th power (which is 10^10), the product would be that number with 10 zeros added to the end.
Please confirm if you were referring to multiplying by 10^10 or another power of 10, or if there's a different context for the question!
