Question

expand ( x+4)power 3​

Answer 1

Answer: The answer is x³+64

Answer 2

${(x + 4)}^{3}$

$\large \sf \green {\boxed {We\: know \:that\: -}}$

$\green{{(a + b)}^{3} = {a}^{3} + {b}^{3} + 3ab(a + b)}$

${x}^{3} + {4}^{3} + 3 \times x \times 4(x + 4)$

$= {x}^{3} + 64 + 12x(x + 4)$

$= {x}^{3} + 64 + 12 {x}^{2} + 48x$
