p^Log akar q=4, r^Log q=8. Pqr^Log q ^15=

p log √q = 4
p log √q = p log p⁴
√q = p⁴
q² = p ...(1)

r log q = 8
r log q = r log r^8
q = r^8 ...(2)

subtitusi (2) ke (1)
q² = p
(r^8)² = p
r^16 = p ...(3


pqr^log q^15
= (r^16)(r^8)r log (r^8)^15
= r^25 log r^120
= 120/25 (r log r)
= 24/5 (1)
= 4,8

Maaf yaa klo salah
