Question

Find the value of the expression a3(power3) + b3(power3) + c3(power3) – 3abc for a = 2, b = 3, c = 4

Answer 1

Expression provided with us:

$\rm\implies {a}^{3} + {b}^{3} + {c}^{3} - 3abc \: ...(1)$

✰ We also know that ༄

$\rm\implies a = 2$

$\rm\implies b =3$

$\rm\implies c = 4$

✰Now ༄

➡ Substitute the value of a,b,c in equation (1) and solve

$\longrightarrow\bigstar \: \: \sf\boxed{\bold{\orange{ {(2)}^{3} + {(3)}^{3} + {(4)}^{3} - 3(2)(3)(4) }}}\: \: \: \bigstar$

$\longrightarrow\bigstar \: \: \sf \boxed{\bold \blue{{8 + 27 + 64 - 72}}}\: \: \: \bigstar$

$\longrightarrow\bigstar \: \: \sf\boxed{\bold{\red{35 + 64 - 72}}}\: \: \: \bigstar$

$\longrightarrow\bigstar \: \: \sf\boxed{\bold{\pink{99 - 72 }}}\: \: \: \bigstar$

$\longrightarrow\bigstar \: \: \sf\boxed{\bold{\blue{27}}}\: \: \: \bigstar$

✰Thus ༄

Answer 2

Answer:

Thanks for your question...

Your required answer :

Given :

• Equation =
• $b {}^{(3) {}^{3} } + c { {}^{(3)} }^{3} - 3abc$
• a = 2
• b = 3
• c = 4

Solving :

• b⁹ + c⁹ - 3abc
• (3)⁹ + (4)⁹ - 3 × 2 × 3 × 4
• 19683 + 262144
• 281827 - 72
• 281755
