Answer:
1.) (5x⁴-3x²+4) +(6x³-4x²-7)
=11x⁷+7x-11
=18x⁸-11
2.) -7x³y+4x²y²-2 and 4x³y+1-8x²y²
=11xy-12xy-3
=-23x²y²-3
3.)(5+24y³-7y²)+(-6y³+7y²+5)
=30y-14y+10
=44y²+10
4.)(2x⁵-6x³-12x²-4)+(-11x⁵+8x+2x²+6)
=-13x+14x⁴-14x+10
=27x+14x⁴+10
5.)(3y⁵-2y+y⁴+5) and (2y⁵+3y³+2+7)
=5y¹⁰-5y³+2y⁴+12
=-10y⁷+2y⁴+12
=-12y³+12
