Step-by-step explanation:

mark brainliest pls :D

Answer 2

Answer:

a

Step-by-step explanation:

$x^{m}*a^{n}=a^{m+n}$

In exponent multiplication, if bases are same add the powers.

9 p q r³ * (-4 p²rs) *qr = (9*[-4] ) * p*p² * q*q *r³*r*r *s

                               = -36 p¹⁺² * q¹⁺¹ * r³⁺¹⁺¹ * s

                               = -36 p³q²r⁵s
