Question

Evaluate:

(i)$\left(4\right)\times \left(7p\right)$

(ii)$(-4p)\times \left(7p\right)$

(iii)$(-4p)\times \left(7pq\right)$

(iv)$\left(4p^3\right)\times (-3p)$

(v)$\left(4p\right)\times \left(0\right)$

Answer 1

(i)$\left(4\right)\times \left(7p\right)=28p$

(ii)$(-4p)\times \left(7p\right)=-28p^2$

(iii)$(-4p)\times \left(7pq\right)=-28p^{2}q$

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

(v)$\left(4p\right)\times \left(0\right)=0$
