Answer:
320[tex]x^{6}[/tex]
Step-by-step explanation:
Using the rules of exponents
• [tex](ab)^{n}[/tex] ⇔ [tex]a^{n}[/tex] [tex]b^{n}[/tex]
• [tex]a^{m}[/tex] × [tex]a^{n}[/tex] ⇔ [tex]a^{(m+n)}[/tex]
simplifying [tex](4x)^{3}[/tex] = 4³ × x³ = 64x³
(5x³) ×[tex](4x)^{3}[/tex]
= 5x³ × 64x³ = (5 × 64) × (x³ × x³) = 320[tex]x^{(3+3)}[/tex] = 320[tex]x^{6}[/tex]
