Tolong beserta caranya ya.. Trims Nomor 5,6,dan 9

keterangan: '(pangkat)
5. c
= (3c/4ab'5)'-2 × (a'4c'-1/4b'3)'2
= (4ab'5/3c)'2 × (a'4c'-1/4b'3)'2
= (4ab'5/3c × a'4c'-1/4b'3)'2
= (ab'2/3c'2 × a'4)'2
= (a'5b'2/3c'2)'2
= a'10b'4/9c'4

6. e
= (x+2)'2 × (x+2)'3/(x-3)'3 × (x'2-2x-3x+6/(x-2)(x+2))'4
= (x+2)'2 × (x+2)'3/(x-3)'3 × (x(x-2)-3x(x-2)/(x-2)(x+2))'4
= (x+2)'2 × (x+2)'3/(x-3)'3 × (x-3/x+2)'4
= (x+2)'2 × (x+2)'3/(x-3)'3 × (x-3)'4/(x+2)'4
= (x+2)'3 × x-3/(x+2)'2
= (x+2)(x-3)
= x'2 - 3x + 2x - 6
= x'2 - x - 6

9. d.... (CARANYA DIGAMBAR/LAMPIRAN)
salah maaf....
