Determine (8x)^(x), if 9^(x+2)=240+9^(x)

Determine (8x)^x , if 9^(x+2)=240+9^x

The domain of the function (x^(2) + 8x + 9)/(x^(2) - 9x + 20) is

The domain of the function (x^(2) + 8x + 9)/(x^(2) - 9x + 20) is

Determine the intervals of monotonicity for the following functions : f(x) = 2x^(3) -9x^(2) -24x +7 ,

Simplify the following : 5x^(4) - 7x^(2) +8x - 1 +3x^(2) - 9x^(2) + 7 - 3x^(4)+11x - 2 +8x^(2)

The centre of circle inscribed in a square formed by lines x^(2)-8x+12=0 and y^(2)-14y+45=0 is (4,7)(7,4)(9,4)(4,9)

The sum of 5x^(2) ,7x^(2) ,8x^(2) ,11x^(2) and 9x^(2) is …………..
