Answer 1

Step-by-step explanation:

ii). 7p⁴(49p⁸-7p⁴q+q²) + q(49p⁸-7p⁴q+q²)

= 343p¹²-49p⁸q+7P⁴q² + 49p⁸q-7p⁴q²+q³

= 343p¹²+q³

= (7p⁴)³ + q³

iii). 3/x(9/x²+25/y²+15/xy) - 5/y(9/x²+25/y²+15/xy)

= 27/x³+75/xy²+45x²y - 45/x²y -125y³-75xy²

= (3/x)³-(5y)³

iv). 2/x(4x²+9x²-6) +3x(4x²+9x²-6)

= 8/x³+18x-12/x + 13x³+27x³-18x

= (2/x)³-12/x +40x³

v). x²(x⁴+x²+1)-1(x⁴+x²+1)

= x⁶+x⁴+x² - x⁴+x²-1

= x⁶+2x²-1
