You must say clearly what the 1 and the 2 trailing the P are.

Otherwise, choose your base and go this way:
log%28b%2C%28P%5B1%5D%2BP%5B2%5D%29%29=log%28b%2C%28R%5Ex%29%29
log%28b%2C%28P%5B1%5D%2BP%5B2%5D%29%29=x%2Alog%28b%2CR%29
highlight%28x=log%28b%2C%28P%5B1%5D%2BP%5B2%5D%29%29%2Flog%28b%2CR%29%29
