Answer:
Significant figures are the number of digits in a value, often a measurement, that contribute to the degree of accuracy of the value. We start counting significant figures at the first non-zero digit.
Step-by-step explanation:
348:3072 because you multiply all the original number and then you get 348 and then you double the original number and multiply the doubled number and you get 3072,
There is no difference, both equal 40.
