x=log28x=\log_{2}8x=log28
x=log82x=\log_{8}2x=log82
2=logx82=\log_{x}82=logx8
8=log2x8=\log_{2}x8=log2x
x=logy3x = log_y3x=logy3
x=3logyx = 3logyx=3logy
x=log3yx = log_3yx=log3y
x=ylog3x = y log3x=ylog3
log4x=π\log_{4}x=\pilog4x=π
logπ4=x\log_{\pi}4=xlogπ4=x
logxπ=4\log_{x}\pi=4logxπ=4
logπx=4\log_{\pi}x=4logπx=4
x=57x = 5^{7}x=57
x=75x = 7^{5}x=75
7x=57^{x}=57x=5
7x5=77x^{5}=77x5=7
