2 log x + 2 log y3 = 13 2 log x - 2 log y = 5 nilai x + y= beri penjelasan juga ya makasih :))

²log x + ²log y³ = 13
²log x + 3.²log y = 13
eliminasi
²log x + 3.²log y = 13
²log x - ²log y = 5
---------------------------- _
4.²log y = 8
²log y = 8/4
²log y = 2
y = 2² = 4
²log x - 2 = 5
²log x = 5 + 2
²log x = 7
x = 2^7 = 128
x + y = 128 + 4 = 132
