I have been researching and I know that the difference is 50 but would the correct answer be 50 or 10\5 (10 to 5th power) :)
what is the difference?

also,
two waves meet at the same time when one has the instantaneous amplitude A & the other has the instantanous amplitude B. what is their combined amplitude at this time? (what the heck does this mean? Dummy terms? lol! )

No, the difference is 50dB, not just 50. Yes, 50dB = 10^5 = 100000. The difference between 50 and 50dB is the scale, not the units. dB is a logarithmic scale, whereas just "50" is a purely linear scale.

80= 10logP/Pbase
30 =10 logP´/Pbase
substracting
8O -30 = 10 logP/P´ so 5 = log P/P´ and P/P´= 10^5
