Tolong bantuannya yg no 1

misal: ^2logx=a
^3logy=b

^2logx^2 + ^3logy^-3 = 4
2a -3b =4..(1)

^2logx + ^3logy^4 =13
a + 4b = 13...(2)

eliminasi 1)&2)
2a -3b =4.....(×1
a + 4b = 13...(×2
2a - 3b =4
2a + 8b =26
__________-
-11b = -22
b= 2
2a - 3b =4
2a -3(2) =4
2a =10
a=5

^2logx=a
^2logx=5
x=2^5=32

^3logy=b
^3logy=2
y=3^2=9

maka
^4log32 - ^9log9
[tex]^{2^{2} } log(2 ^{5} ) - ^{9} log(9) \\ \frac{5}{2} - 1 \\ \frac{3}{2} [/tex]

hasilnya E
