Remember your log addition rules.
log%2810%2CA%2AB%29=log%2810%2CA%29%2Blog%2810%2CB%29
Let's make some substitutions.
log%2810%2CA%2A45%29=log%2810%2CA%29%2Blog%2810%2C45%29=12%2Blog%2810%2C45%29
If we equate terms then,
log%2810%2CA%29=12
A=10%5E12
log%2810%2C4.5%2A10%5E%2813%29%29=12%2Blog%2810%2C45%29
