72 * 3 * 3 * 3 = 1944
2 x 2 x 2 x 3 x 3 = 72 2^3 x 3^2 = 72
24 x 3 is 72.
prime factors of 72 = 2 & 3
72 cubed = 72 x 72 x 72 = 373,248 = (3 x 100000) + (7 x 10000) + (3 x 1000) + (2 x 100) + (4 x 10) + (8 x 1)
9 = 3 x 3 6 = 3 x 2 3 = 3 8 = 2 x 2 x 2 LCM = 3 x 3 x 2 x 2 x 2 = 72
The prime factors of 72 are 2x2x2x3x3 (or 23 x 32).
2 x 2 x 2 x 3 x 3 = 72
2 x 2 x 2 x 3 x 3 = 72
72 = 2 x 2 x 2 x 3 x 3
3 x 3 x 3 = 27 2 x 2 x 2 x 3 x 3 = 72
2^3 x 3^2 72 = 2 x 2 x 2 x 3 x 3
ANSWER: -144Let x = the numberEquation:72 + x = 2/3 (x)x - 2x/3 = -72(3x - 2x)/3 = -72x/3 = -72x = 3 * -72x = -216Check:72 + x = 2/3 (x)72 +(-216) = 2(-216)/372 - 216 = -432/3-144 = -144
