tolong jawab nomor empat dan lima terima kasih

(2p + 3)³
[2 3]
[2 3]
[4 6 6 9]
[2 3]
8 12 12 18 12 18 18 27

[p 1]
[p 1]
[p² p p 1]
[p 1]
p³ p² p² p p² p p 1
hasilnya adalah:
8p³ + 12p² + 12p² + 18p + 12p² + 18p + 18p + 27
disederhanakan:
8p³ + 36p² + 54p + 27

4. (2p+3)³
= (2p+3) (2p+3) (2p+3)
= (4p²+6p+6p+9) (2p+3)
= (4p²+12p+9)(2p+3)
= (8p³+12p²+24p²+36p+18p+27)
= 8p³ + 36p² + 54p + 27

5. (a+2b) ⁴
= (a+2b)(a+2b)(a+2b)(a+2b)
= (a²+2ab+2ab+4b²)(a²+2ab+2ab+4b²)
= (a²+4ab+4b²)(a²+4ab+4b²)
= a⁴+4a³b+4a²b²+4a³b+4a²b²+4ab³+4a²b²+4ab³+4b⁴
= a⁴+8a³b+12a²b²+8ab³+b⁴
