Answer 1
Answer:

Answer:

5.00*10^(-5)

Explanation:

(6.32*10^(-4) )/(12.64)  = 0.00005= 5.00*10^(-5)

The answer is in three significant figures because that is the least number of significant figures in any of the numbers involved in the calculation
Answer 2
Answer: Express the answer in scientific notation and with the correct number of significant figures:
