p⁷q⁹r⁸
Step-by-step explanation:
There is a rule in power and indices that is the bases are same the power gets added.
so here the question is p⁴q³r x p³q⁴r⁵ x p⁰q²r²
as we can see in every term p,q,r is present and they are common
then we can take p , q, r, common from alle the 3 terms and apply the rules of power and indices.
- if we see p in all terms P's powers are 4,3,0 , as I said rule of indices above apply that if the bases are same power gets added . now add all powers of p ; so it will become 4+3+0=7. therefore p⁷
- again same for q ; so it will become 3+4+2=9 . therefore q ⁹
- same for r also 1+5+2=8 . therefore r⁸ ( note if power is not given assume it as 1 only always for any variable).
Answer is p⁷q⁹r⁸
