1P2⋅p17

Explanation:

P−2⋅p−8⋅p−9

Add the exponents for common variables
[When exponents over the same variable are multiplying we ADD them]

P−2⋅p−8+(−9)

So,

P−2⋅p−17

Now we move all of the negative exponents into a fraction as the denominator
[Remember everything has a 1 underneath it, we just don't write it because we know it is there]

Think of it like this

P−2⋅p−171

Now move the negative exponents to the denominator so that they become positive
[If there was a positive exponent it would stay in the numerator]

1P2⋅p17
