Question

Find d

a * a * a = 216
a * b * c = 96
b * c = 52
a + b + c = d

Answer 1

`a\cdot a\cdot a=216\\\\a^3=216\to a=\sqrt[3]{216}\\\\\boxed{a=6}\\\\\text{Substitute}\ b\cdot c=52\ \text{to the second expression}\ a\cdot b\cdot c=96:\\\\abc96\ \wedge\ bc=52\to a(52)=96\qquad\text{divide both sides by 52}\\\\a=(96)/(52)\to a=(24)/(13)\\eq6`

a = 6 and a = 24/13 FALSE!!!

Answer: NO SOLUTION.
