Question

Factorisation = t⁹- 512​

Answer 1

Step-by-step explanation:

$t {}^{9} - 2 {}^{9}$

(t+2) (t-2)

Answer 2

Answer:

We know, a³ – b³ = (a – b)(a²+ ab + b²)

Given,

t⁹– 512

= (t³)³ – (8)³

= (t³ – 8) (t⁶ + 8t³ + 64)

= [(t)³ – (2)³] (t⁶+ 8t³ + 64)

= (t – 2) (t² + 2t + 4) (t⁶ + 8t³ + 64)
