Solution and Explanation

(i) a2 \(\times\) (2a22\(\times\) (4a26)
= (2 \(\times\) 4) ( a2 \(\times\) a22 \(\times\) a26 )
= 8 \(\times\) a2 + 22 + 26 
= 8a50


(ii) (\(\frac{2xy}{3}\)\(\times\) (\(\frac{-9x^2y^2}{10}\))

=(\(\frac{2}{3}\) \(\times\) \(\frac{-9}{10}\) ) ( x \(\times\) x2 \(\times\) y \(\times\) y2 )

= (\(\frac{-3}{5}\) x3y3)


(iii) (\(\frac{-10pq^3}{3}\)\(\times\)(\(\frac{6p^3q}{5}\))

= ( \(\frac{-10}{3}\) \(\times\) \(\frac{6}{5}\) ) (p \(\times\) p3\(\times\) q3 \(\times\) q)

= (-4p4q4)


(iv) ( x) \(\times\) (x2\(\times\) (x3\(\times\) (x4)
= x 1 + 2 + 3 + 4 
= x10
