​

Answer 1

Answer:

Algebra

Step-by-step explanation:

a3 = 9

b3 = 6

c3 = 3

2ab = 12

Answer = 6

Answer 2

Answer:

$24$

Step-by-step explanation:

We'll solve the above question by taking the variable as =

$\rightarrow$ a= 3

$\rightarrow$ b= 2

$\rightarrow$ c= 1

‎ ‎

${a}^{3} + {b}^{3} + {c}^{3} - 2ab \\ \\ = {3}^{3} + {2}^{3} + {1}^{3} - 2(3 \times 2) \\ \\ = 27 + 8 + 1 - 12 \\ \\ = 27 +9- 12\\ \\ = 36-12 \\ \\ = 24$
