`x=(2*5)/((2!)3)+(2*5*7)/((3!)3^(2))+(2*5*7*9)/((4!)3^(3))+.....` then `x^(2)+8x+8=`

(2x)/(5-3x)=(5+3x)/(8x)

(2x+7)/(5)-(3x+11)/(2)=(2x+8)/(3)-5

X+7-(8X)/(3)=(17)/(6)-(5X)/(2)

(6x-7)/(2)+(9-2x)/(5)=12+(x)/(4)-(2)/(3)+(4x)/(3)

(v) (3)/(8)+(7)/(2)+((-3)/(5))+(6)/(5)-((-9)/(8))-(3)/(2)

Simplify: ((3)/(2)x(1)/(6))+((5)/(3)x(7)/(2))-((13)/(8)x(4)/(3))

Simplify : (5/8)^(-7)x\ (8/5)^(-5) (ii) ((-2)/3)^(-2)x\ (4/5)^(-3) (3/4)^(-4)-:(3/2)^(-3) (iv) (3/7)^(-2)x\ (7/6)^(-3)

Evaluate int((8x+13)/(sqrt(4x+7)))dx(A)(1)/(3)(4x+7)^((3)/(2))-(1)/(2)(4x+7)^((1)/(2))+c(B)(1)/(6)(4x+7)^((5)/(2))-(2)/(3)(4x+7)^((3)/(2))+c(C)(1)/(3)(4x+7)^((5)/(2))-(1)/(2)(4x+7)^((3)/(2))+c(D)(4x+7)^((3)/(2))-(1)/(2)(4x+7)^((1)/(2))+c

Subtract: (i) 5a + 7b - 2c from 3a - 7b + 4c (ii) a - 2b - 3c from -2a + 5b - 4c (iii) 5x^(2) - 3xy + y^(2) from 7x^(2) - 2xy - 4y^(2) (iv) 6x^(3) - 7x^(2) + 5x - 3 from 4 - 5x + 6x^(2) - 8x^(3) (v) x^(3) + 2x^(2) y + 6xy^(2) - y^(3) from y^(3) - 3xy^(2) - 4x^(2) (vi) -11 x^(2) y^(2) + 7xy - 6 from 9x^(2) y^(2) - 6xy + 9 (vii) -2a + b + 6d from 5a - 2b - 3c
