Answer 1

$\LARGE\tt{}\left(x + 4\right)^{3} \\\\ \LARGE\tt{} {x}^{3} + {3x}^{2} \times 4 + 3x \times {4}^{2} + {4}^{3} \\\\ \LARGE\tt{} {x}^{3} + {12x}^{2} + 3x \times {4}^{2} + {4}^{3} \\ \\ \LARGE\tt{} {x}^{3} + {12x}^{2} + 3x \times 16 + {4}^{3} \\ \\ \LARGE\tt{} {x}^{3} + {12x}^{2} + 3x \times 16 + 64 \\ \\\LARGE\tt{} \LARGE\tt{} \boxed{ {x}^{3} + {12x}^{2} + 48x + 64 }$
