1: (5×⁶+4y²)²

=(5x⁶)²+2.(5x⁶).(4y²)+(4y²)²

=25x¹²+40x⁶y²+16y⁴


2: (7x²y⁴-2)

= (7x²y⁴)²-2.(7x²y⁴).2+2²

= 49x⁴y⁸-28x²y⁴+4


3:. (6x³/z⁴ + 5)²

=(6x³/z⁴)² +2 . (6x³/z⁴).5+5²

36x⁶/z⁸ + 60x³/z⁴ + 25


4:. (4x²/z³ -3)²

=(4x²/z³)² -2.(4x²/z³).3+3²

=16x⁴/z⁶ - 24x²/z³+9


5:. (3x⁸+2y⁴)³

= (3x⁸)³+3.(3x⁸)².(2y⁴)-3.(3x⁸).(2y⁴)²+(2y⁴)³

=3.3.3=27 3.3.3.2=54 3.3.2.2=36. 2.2.2=8

=(3x⁸+2y⁴)³=

27x²⁴+54x¹⁶y⁴ - 36x⁸y⁸ + 8y¹²


6:. (5x⁶/y⁴+4)³

=(5x⁶/y⁴)³+3.(5x⁶/y⁴)².4+3.(5x⁶/y⁴).5²+5³

=5.5.5=125 3.5.5.4=300. 3.5.5.5=375. 5.5.5=125

=(5x⁶/y⁴+4)³

= 125x¹⁸/y¹² +300x¹²/y⁸+375x⁶/y⁴+125



7:. (4x³+3y⁹)³

=(4x³)³+3.(4y³)².(3y⁹)-3.(4x³).(3y⁹)²+(3y⁹)3

4.4.4=64. 3.4.4.3=144. 3.4.3.3=108. 3.3.3=27

(4x³+3y⁹)³

=64x⁹+144x⁶y⁹-108x³y¹⁸+27y²⁷



8:(2p⁴/q³ -5)³

=(2p⁴/q³)³-3.(2p⁴/q³)².5-3.(2p⁴/q³).5²-5³


2.2.2=8. 3.2.2.5=60. 3.2.5.5=150. 5.5.5=125


(2p⁴/q³-5)³=

8p¹²/q⁹-60p⁸/q⁶+150p⁴/q³-125.
