Two cells are viewed and measured under a microscope. The approximate diameter of each cell is listed.
Cell P: 5.0×10^−4 m
Cell Q: 3.0×10^−5 m
Which expression would you use to find the difference between the two diameters?
A. (5.0×10^−4)−(3.0×10^−5)
B. (3.0×10^−5)(5.0×10^−4)
C. (5.0×10^−4)÷(3.0×10^−5)
D. (3.0×10^−5)÷(5.0×10^−4)
E. (3.0×10^−5)−(5.0×10^−4)
F. (5.0×10^−4)(3.0×10^−5)
