Physics help soon please?

Experimenters at the National Institute of Standards and Technology have made precise measurements of the speed of light using the fact that, in vacuum, the speed of electromagnetic waves is c = 1/√(µ0ε0), where the constants µ0 = 4π multiplied by 10-7 N · s2/C2 and ε0 = 8.854 multiplied by 10-12 C2/N · m2. What value (to four significant figures) does this give for the speed of light in vacuum?
