Answer 1

$1) \ x^{40} =x^{9} \cdot \boxed{x^{8}}\cdot x^{23} \\\\2) \ \boxed{a^{13}} \cdot a^{5}\cdot a^{23}=a^{41}\\\\3) \ \boxed{(ab)^{4}}\cdot (ab)\cdot (ab)^{9}=(ab)^{14}\\\\4) \ \Big(\dfrac{c}{4} \Big)^{20}\cdot \boxed{ \Big(\dfrac{c}{4} \Big)^{6}}= \Big(\dfrac{c}{4} \Big)\cdot \Big(\dfrac{c}{4} \Big)^{25} \\\\\\5) \ (-k)^{5}\cdot \boxed{(-k)^{10}}=(-k)^{15}$

$6) \ \Big(\dfrac{2}{5}y \Big)^{6}\cdot \boxed{\Big(\dfrac{2}{5}y \Big)^{3}}= \Big(\dfrac{2}{5}y \Big)\cdot \Big(\dfrac{2}{5}\Big)^{8}$
