Answer:
Red Cell is 300 times larger than the virus
Step-by-step explanation:
Size in scientific Notation
Red Cell = 9 * 10^-6 Virus = 9 * 10^-8 Procedure.
Count the number of zeros in the decimal Red Cell = 5 ; virus = 7 And one more to each Red Cell = 6; virus = 7 change the numbers to minus Red Cell = -6 ; virus = - 7 The last row is the powers as shown above. Answer
9*10^-6/3 * 10^-8
3*10^(-6 - - 8)
3*10^(- 6 + 8)
3^10^2 or 300 times larger
Answer:
3*10^2
