Answer 1

c)= 5³(5²+5-30)=5³(25+5-30)=5³x0=0
d)=2ⁿ+2ⁿx2+2ⁿx2²+2ⁿx2³=2ⁿ(1+2+4+8)=2ⁿx15
e)=2ⁿx2⁵-2ⁿx2⁴-2ⁿx2³=2ⁿ(2⁵-2⁴-2³)=2ⁿx(32-16-9)=2ⁿx7
f)=3ⁿx5ⁿx5²+3ⁿx3²x5ⁿ-3ⁿx3x5ⁿx5=3ⁿx5ⁿ(25+9-15)=15ⁿx19
g)=12ⁿx12+3ⁿx4ⁿx4-3ⁿx3²x4ⁿ=12ⁿx12+12ⁿx4-12ⁿx9=12ⁿ(12+4-9)=12ⁿx7
h)=3ⁿx3³x4ⁿ+3ⁿx3x4ⁿx4²-3ⁿx3²x4ⁿx4=12ⁿx27+12ⁿ48-12ⁿx36=12ⁿ(27+48-36)=
=12ⁿx39
