(3p²qr³)*(-4p³qr²)*(7pq³r) = -84 p⁶ q⁵ r⁶
Step-by-step explanation:
(3p²qr³)*(-4p³qr²)*(7pq³r)
Concept to be used here
xᵃ * xᵇ = xᵃ⁺ᵇ
Lets arrange terms
= (3)(-4)(7) (p²p³p) (qqq³) (r³r²r)
= -84 (p²p³p¹) (q¹q¹q³)(r³r²r¹)
now using xᵃ * xᵇ = xᵃ⁺ᵇ
= -84 p²⁺³⁺¹ * q¹⁺¹⁺³ * r³⁺²⁺¹
= -84 p⁶ q⁵ r⁶
(3p²qr³)*(-4p³qr²)*(7pq³r) = -84 p⁶ q⁵ r⁶
