(10m. Sax (20.5%(4.3, 4p)​

Answer 1

solution : (i) 4\times7p=4\times7\times p=28p4×7p=4×7×p=28p

(ii) -4p\times7p=\left(-4\times7\right)\times\left(p\times p\right)=-28p^2−4p×7p=(−4×7)×(p×p)=−28p

2

(iii) -4p\times7pq=\left(-4\times7\right)\left(p\times pq\right)=-28p^2q−4p×7pq=(−4×7)(p×pq)=−28p

q

(iv) 4p^3\times-3p=\left(4\times-3\right)\left(p^3\times p\right)=-12p^44p

3

×−3p=(4×−3)(p

3

×p)=−12p

please mark me brainlest

(v) 4p\times0=\left(4\times0\right)\left(p\right)=04p×0=(4×0)(p)=0
