Multiply. 18x^4y^2/4 a^5b^3 middot 16a^7 b/9 x^8 y^4 10x^2 - 30x/3x + 12 middot 5x + 20/6x - 2x^2 Divide 7x^4 + 9 x^3/4x - 10 7x^3 + 9x^2/16x - 40 6. Pq^5/p^2 + 5p - 36 p^3q^2/p^2 - 7p + 12

Solution

3.   (18x⁴y²/4a⁵b³).(16a⁷b/9x⁸y⁴) = (18x⁴y²/9x⁸y⁴)( 16a⁷b/4a⁵b³) = (2x^4-8 y^2-4).(4a^7-5b^1-3) = 8a²/b²x⁴y²

4. [(10x²-30x)/(3x+12)].[(5x+20)/(6x-2x²)] = [10x(x-3)/3(x+4)]. [5(x+4)/2x(3-x)] = (50x/6x) [(x-3)(x+4)/(x+4)(3-x)] = (25/3)(-1) = -25/3.

5. [(7x⁴+9x³)/(4x-10)]/ [ (7x³+9x²)/(16x-40)] = [x³(7x+9)/ 2x(2x-5)].[ 8x(2x-5)/x²( 7x+9)] = (8x⁴/2x³)[(2x-5)/(2x-5)]*[(7x+9)/(7x+9)] = 4x.

6. [pq⁵/(p² +5p-36)]/[ p³q²/(p² -7p+12)] = (pq⁵ / p³q²)[ (p-3)(p-4)/(p+9)(p-4)] = q³(p-3)/p²(p+9)
