Factorise a⁷–64a find the answer

Answer 1

Answer:

Hello, Good Afternoon...

Step-by-step explanation:

Factorize the following -

a^7 - 64a..

By using the Common Factor Method, we get,

a^7 = a*a*a*a*a*a*a*a

(-64a) = (-1)*2*2*2*2*2*2*a [By finding the Prime actors of the number -64...]

Here, you find "a" as common in both.

Therefore, split "a" from the others...

You get "a [a^6 - 64] as the answer...

Answer 2

Answer:

a⁷- 64a

= a( a⁶ - 64)

= a [(a³)² - (8)²]

= a (a³- 8) (a³+ 8)

= a (a³- 2³) (a³+ 2³)

= a (a-2)(a²+2a+4)(a+2)(a²-2a+4)
