If no. of protons in `X^(-2)` is `16`. Then no. of `e^(-)` in `X^(+2)` will be-

The atomic number of an element 'X' is 16.The no. of electrons in its ion E^(2-) will be

int (e ^ (2x) -e ^ (- 2x)) / (e ^ (2x) + e ^ (- 2x)) dx

The charge on a proton is +1.6 X 10(-19) C and that on an . electron is -1.6 X 10 (-19)C. Does it mean that the electron . has a charge 3.2 X 10(-19) c less than the charge of a . proton?

The range of the function f(x) = log _e (2 (2- log _( sqrt2) (16 sin ^(2) x+1) ) )

If e_(1) and e_(2) be the eccentricities of the hyperbolas 9x^(2) - 16y^(2) = 576 and 9x^(2) - 16y^(2) = 144 respectively, then -

The function f(x)=e^(x+1)(4x^2-16x+11) is :

The number of solution of the equation e^(2 x) + e^x+e^-(2 x)+ e^(-x)=3(e^(-2 x) + e^x) is

If log(x^(2) - 16) le log_(e) (4 x -11) , then
