Odgovor:
# 14sqrt (2) #
Obrazloženje:
#color (plava) (32 = 4 ^ 2 * 2 rarr sqrt (32) = 4sqrt (2)) #
#color (crveno) (50 = 5 ^ 2 * 2 rarr sqrt (50) = 5sqrt (2)) #
#color (zelena) (18 = 3 ^ 2 * 2 rarr sqrt (18) = 3sqrt (2)) #
Stoga
#COLOR (bijeli) ("XXX") 2color (plavo) (sqrt (32)) + 3color (crvena) (sqrt (50)) - 3color (zeleno) (sqrt (18)) *
#COLOR (bijeli) ("XXX") = 2 * boja (plava) (4sqrt (2)) + 3 * boja (crvena) (5sqrt (2)) - 3 * boja (zeleno) (3sqrt (2)) *
#COLOR (bijeli) ("XXX") = 8sqrt (2) + 15sqrt (2) -9sqrt (2) #
#COLOR (bijeli) ("XXX") = 14sqrt (2) #
