Answer:Step-by-step explanation:
Step-by-step explanation:a^7 - 64a
Step-by-step explanation:a^7 - 64a= a(a^6 - 64)
Step-by-step explanation:a^7 - 64a= a(a^6 - 64)= a{(a³)² - (2³)²}
Step-by-step explanation:a^7 - 64a= a(a^6 - 64)= a{(a³)² - (2³)²}= a{(a³+2³)(a³-2³)
Step-by-step explanation:a^7 - 64a= a(a^6 - 64)= a{(a³)² - (2³)²}= a{(a³+2³)(a³-2³)= a[{(a+2)(a²-2a+4)}{(a-2)(a²+2a+4)}]
