To find the difference between the diameters of Cell P and Cell Q, you would use the subtraction operation.
Given:
- Cell P: \( 5.0 \times 10^{-4} \) m
- Cell Q: \( 3.0 \times 10^{-5} \) m
You would subtract the diameter of Cell Q from the diameter of Cell P:
\[ (5.0 \times 10^{-4}) - (3.0 \times 10^{-5}) \]
So the correct expression to find the difference between the two diameters is:
(5.0×10−4)−(3.0×10−5)
