8. x3 + xyz +y3​

Answer 1

Answer:

ab+bc+ca

Explanation:

hope it will help you

Answer 2

1. Mathematic expression:-

$\sf ab + bc + ca$

1. Java Expression:-

$\sf{}(a*b) +(b*c) + (c*a)$

2. Mathematic expression:-

$\sf {a}^{2} + ab - {b}^{2}$

2. Java Expression

$\sf(a*a) + (a*b) - (b*b)$

or

$\sf{}Math.pow(a,2) + (a*b) -Math.pow{} (b,2)$

3. Mathematical Expression :

$\sf{}ut + \dfrac{1}{2a {t}^{2} }$

3. Java Expression :

$\sf{}(u*t) + 1/(2*a*t*t)$

4. Mathematical Expression:

$\sf \dfrac{uv}{u + v}$

4. Java Expression:

$\sf{}(u*v)/(u+v)$

5. Mathematical Expression:

$\sf(a + b)n$

5. Java Expression:

$\sf(a + b)*n$

6. Mathematical Expression:

$\sf2(lb+bh+lh)$

6. Java Expression:

$\sf2*((l*b)+(b*h)+(l*h))$

7. Mathematical Expression:

$\sf{} {a}^{2} + {b}^{2}$

7. Java Expression:

$\sf{}( {a}*a) + (b*b)$

or

$\sf{}Math.pow( a,2)+Math.pow(b,2)$

8. Mathematical Expression:

$\sf{} {x}^{3} + xyz + {y}^{3}$

8. Java Expression:

$\sf{}( x*x*x)+ (x*y*z )+(y*y*y)$

or

$\sf{}Math.pow( x,3)+ (x*y*z )+Math.pow(y,3)$
