Question

pls answer grade 6 maths question

Answer 1

Answer:

$\bold{(i)}\:yz^2-ab^2$

$\bold{(ii)}\:1$

$\bold{(iii)}\:-3m+8m^2-5m^3$

Step-by-step explanation:

$\bold{(i)}\:\bold{Find\:the \: product\:of}\:(yz-ab)\: \bold{and}\:(yz+ab)$

$\bold{sol:}$- Given,(yz - ab) and (yz + ab)

      $\Rightarrow yz(yz+ab)-ab(yz+ab)$

      $\Rightarrow yz^2 +yzab - abyz-ab^2$

      $\Rightarrow yz^2-ab^2+yzab-yzab$

      $\Rightarrow yz^2-ab^2$

________________________

$\pink{\mathfrak{Final\:answer:-}}\boxed{yz^2-ab^2}$

$\bold{(ii)}\:\bold{Divide\: -15p^6q^8 \:by\:-15p^6q^8}$

$\bold{sol:}$- Given,$(-15p^6q^8) \:\bold{by}\:(-15p^6q^8)$

      $\Rightarrow \frac{-15p^6q^8}{-15p^6q^8}$

      $\Rightarrow 1$

$\pink{\mathfrak{Final\:answer:-}}\:\boxed{1}$

________________________

$\bold{(iii)\:Divide}\:6m^2-16m^3+10m^4\:\bold{by}\:-2m$

$\bold{sol:}$-$Given,(6m^2-16m^3+10m^4)\:\bold{by} (-2m)$

      $\Rightarrow \frac{6m^2-16m^3+10m^4}{-2m}$

      $\Rightarrow -3m+8m^2-5m^3$

$\pink{\mathfrak{Final \:answer:-}\boxed{ -3m+8m^2-5m^3}$
