Tolong dong nomor 6 dan 7 makasih

3^✓x^3+2x-4 - 9^✓x^2+x+5=0
3^✓x^3+2x-4 =9^✓x^2+x+5
3^✓x^3+2x-4 = 3^2^✓x^2+x+5
(✓x^3+2x-4)^2=( 2✓x^2+x+5)^2
x^3+2x-4=4(x^2+x+5)
x^3+2x-4=4x^2+4x+20
x^3-4x^2+2x-4x=20+4
x^3-4x^2-2x=24
x(x^2-4x-2)=24
x=24


no.7
p✓64^p-1=r✓4^2p
64^(p-1)/p=4^2p/r
4^3^(p-1)/p=4^2p/r
3(p-1)/2=2p/r
(3p-3)/2=2p/r
r(3p-3)=2(2p)
3rp-3r=4p
3rp=4p+3r

sampe itu aja yg saya tau.

7) 3^r = 3^2(p-2r)
r = 2p - 4r
5r = 2p
p = 5r/2

64^(p-1 / p) = 4^(2p/r)
(2^6)^(p-1 / p) = (2^2)^(2p/r)
2^6(p-1 / p) = 2^2(2p/r)
6(p-1 / p) = 2(2p/r)
(6p-6)/p = 4p/r
ganti p = (5r/2)
(6(5r/2) - 6)/(5r/2) = 4(5r/2)/r
(30r/2 - 6)/(5r/2) = (10r)/r
15r - 6 = 10 × 5r/2
15r - 6 = 25r
15r - 25r = 6
-10r = 6
r = 6/-10 = -3/5
