Answer 2

Step-by-step explanation:

$i) 14x^{5} + 12x^{3} -42+13-15x^{3} +10x^{5}+36$$=14x^{5} +10x^{5}-42+36 + 13+12x^{3}-15x^{3}$
$=24x^{5} + 7-3x^{3}$

$ii) 4x^{2} -18xy+36x^{2} -62xy+9+x^{2} -10+70xy$$=4x^{2}+36x^{2}+ x^{2} -18xy -62xy+70xy+9-10$
$=41x^{2}-10xy-1$
$iii) 32x^{7} +7x+21x+7x^{7} +x^{7}$
$=32x^{7} +7x^{7} +x^{7}+7x+21x$
$=39x^{7} +29x$
