use log+A%2Fb+=+log%28+A%29+-+log%28+B%29. .......the division rule

a. log+%284%2C11%29
first write 11 as 22%2F2, and do so with all other problems

log+%284%2C11%29=+log%284%2C+22%29+-+log%28+4%2C2%29

b.log+%283%2C12%29
log+%283%2C12%29=+log%283%2C+24%29+-+log%28+3%2C2%29


c. log+%289%2C5%29
log+%289%2C5%29=+log%289%2C+10%29+-+log%289%2C2%29


d.
log+%286%2C7%29
log+%286%2C7%29=+log%286%2C+14%29+-+log%286%2C2%29


e. log+%2811%2C21%29
log+%2811%2C21%29=+log%2811%2C+42%29+-+log%2811%2C2%29


f. log+%282%2C13%29
log+%282%2C13%29=+log%282%2C+26%29+-+log%282%2C2%29
