a)  - + 3y
b)9v²n⁴ + 3vn⁴ - 8v²n⁴ + 5vn⁴ 
c)10u³z - 14q⁴s + 6q⁴s + u³z
d)18w¹² . (-3w⁷)  
e)(15b¹²t³) . (3bt³) 
f)(-128x³y⁴) ÷ (-64xy²) 
g)(-2m¹⁰n⁶)⁵ 
h)(p²⁰a⁴⁵)⁴

Answer 1

b)9v²n⁴ + 3vn⁴ - 8v²n⁴ + 5vn⁴ 
9v²n⁴ -  8v²n⁴  + 3vn⁴  + 5vn⁴ 
v²n⁴ + 8 vn⁴
vn⁴.(v + 8)


c)10u³z - 14q⁴s + 6q⁴s + u³z
10u³z + u³z  - 14q⁴s  + 6q⁴s
11u³z  - 8 q⁴s

d)18w¹² . (-3w⁷)  
- 54w¹⁹

e)(15b¹²t³) . (3bt³) 
45b¹³t⁶


f)(-128x³y⁴) ÷ (-64xy²) 
+ 2 x²y²

g)(-2m¹⁰n⁶)⁵ 
- 2m⁵⁰n³⁰


h)(p²⁰a⁴⁵)⁴
p⁸⁰a¹⁸⁰
