Physics, Chemistry, Mathematics Forums

can anyone please tell me what is L HOSPITAL RULE

For the question
xⁿ+yⁿ=zⁿ

what can be the values for x,y,z to make the equation mentioned above equal each other , where x to the n^th power + y to the n^th power equals z to the n^th power where n is greater than 2





This is called Fermat's last Theorem. I couldn't solve this ant thus asked the Forum.

In the circuit shown below the coil has inductance and resistance. When X is joined to Y the time constant is t₀ during growth of current.When the steady state is reached heat is produced in coil at a rate P. X is now joined to Z.

(a) The total heat produced in the coil is Pt₀

(b)The total heat produced in the coil is Pt₀/2

(c)The total heat produced in the coil is 2Pt₀

(d)Data insufficient.

a--------inductor----------------b         in the circuit all places srarting with

a-------||---------Y-                           the same letter are joined together.

                             -X----b               Ex. all points starting with 'a' are

a-------------------Z-                          connected.

  xⁿ + yⁿ = z<sup>n

where n>2 nd x,y,z are not equal to zero</sup>

Could some one explain me the different kinds of addition reaction in organic chemistry in detail.(also with example)
Will be grateful.

X² - Y² + 4X = 0

IF WE SOLVE THE EQN ,WE GET THE EQN OF A HYPERBOLA WITH ECCENTRICITY = 0.

CAN ANY ONE EXPLAIN IF A HYPERBOLA CAN HAVE ECCEN.= 0.

IF IT IS POSSIBLE CAN YOU SHOW IT GRAPHICALLY

BaCO₃ + H₂SO₄  --------> GAS(X)

CH₂=CHBr + Mg/ether + X + WATER + LiAlH₄ + HBr + ozonolysis  --------------> P

TELL ALL POSSIBLE ANSWERS FOR P IN THE ABOVE PROCEDURE

(NOTE THE CARBON IN BARIUM CARBONATE IS SPECIFICALLY UNDERLINED TO DISTINGUISH IT FROM THE OTHER CARBON .DO THE SAME IN THE ANSWER ALSO)
