Menjawab:
# 14sqrt (2) #
Penjelasan:
#color (blue) (32 = 4 ^ 2 * 2 rarr sqrt (32) = 4sqrt (2)) #
#color (red) (50 = 5 ^ 2 * 2 rarr sqrt (50) = 5sqrt (2)) #
#color (hijau) (18 = 3 ^ 2 * 2 rarr sqrt (18) = 3sqrt (2)) #
Karena itu
#color (white) ("XXX") 2color (biru) (sqrt (32)) + 3color (merah) (sqrt (50)) - 3color (hijau) (sqrt (18)) #
#color (white) ("XXX") = 2 * warna (biru) (4sqrt (2)) + 3 * warna (merah) (5sqrt (2)) - 3 * warna (hijau) (3sqrt (2)) #
#color (white) ("XXX") = 8sqrt (2) + 15sqrt (2) -9sqrt (2) #
#color (white) ("XXX") = 14sqrt (2) #
