First we use the power rule to get
log%285%2Cx%5E3%29+-+log%285%2C4%29+=+log%285%2C16%29
next, when we subtract logs, we divide the information to get
log%285%2Cx%5E3%2F4%29+=+log%285%2C16%29
third, eliminate the logs to get
x%5E3%2F4+=+16
multiply by 4 to get
x%5E3+=+64
taking a cube root we get
x+=+4
