First calculate XV (15) squared then multiply this by XV which in effect is XV cubed. XV squared = X(XV)+V(XV) Multiplying out the brackets = CL+LXXV When simplified = CCXXV XV times CCXXV = X(CCXXV)+V(CCXXV) Multiplying out the brackets = MMCCL+DDLLXXV When simplified = MMMCCCLXXV Therefore XV cubed = MMMCCCLXXV (3375) David Gambell, Merseyside, England.
