(8x-2)/(x-3)+(x-4)/(x-5)=(10)/(3),x=

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

Check whether the following are quadratic equations : (1) (x-3)^(2)=x(2x-5) (2) (2x-3)(8x+1) = (4x+5)(4x-5) (3) (5x+3)(x-2)=(4x+3)(2x-1) (4) (2x+5)^(3)=8(x-1)^(3) (5) x^(2)+7x-8=x(x+5) (6) x^(3)+9x^(2)-7x+2=(x+3)^(3)

" If (3x^(3)-8x^(2)+10)/((x-1)^(4))=(3)/(x-1)+(1)/((x-1)^(2))-(7)/((x-1)^(3))+(k)/((x-1)^(2)) then "k=

Obtain the differential coefficient of the following : (i) (x-1) (2x+5) (ii) (9x^(3)-8x+7)(3x^(2)+5) (iii) 1/(2x+1) (iv) (3x+4)/(4x+5) (v) (x^(2))/(x^(3)+1)

If (5x-7)/(3)+2 =(4x-3)/(4)+4x , then the value of (8x+5) is

Simplify and write the answer in the exponential form : (2^5-:2^8)^5x\ 2^(-5) (ii) (-4)^3x\ (5)^(-3)x\ (-5)^(-3) 1/8x\ 3^(-3)

Differentiate the following functions: 12. 8x^(3) - x^(2) + 5 - (2)/( x ) + (4)/( x^3) .

Find the value of x:y, if (8x-10y)/(3x+4y) = (4)/(5) .

Simplify : 15x-[8x^(2)+3x^(2)-{8x^(2)-(4-2x-x^(3))-5x^(3)}-2x]
