Answer 1

Answer:

10.00

Step-by-step explanation:

Let a = 1.5, b = 4.7 and c = 3.8

Then, the given expression is:

\frac{a^3 + b^3 + c^3 - 3abc}{a^2 + b^2 + c^2 - ab - bc - ac}

Now, a^3 + b^3 + c^3 - 3abc = (a + b + c)(a^2 + b^2 + c^2 - ab - bc - ac)

So, the expression is equivalent to:

a + b + c = 1.5 + 4.7 + 3.8 = 10.0
