The vectors `(1,1,m)` , `(1,1,m+1)` and `(1,-1,m)` are non-coplanar, then the number of value(s) of `m` is/are

The speed of six different molecules in a gas are 25 m s^(-1), 20 ms^(-1), 30 m s^(-1), 15 m s^(-1), 10 m s^(-1) and 25 m s^(-1) . Calculate the average speed and also the root mean square of the gas.

If m^2-4m+1=0 then the value of (m^3+1/m^3) is:

The line joining the points (2m + 2 , 2m) and (2m + 1, 3) passes through (m +1 , 1) , if the values of m are "_______" .

For non-negative integers m and n a function is defined as follows: f(m,n)={n+1, if m=0 and f(m-1,1) if m!=0,n=0 and f(m-1,f(m,n-1)) if m!=0,n Then the value of f(1,1) is:

If the roots of the equation (x(x-1)-(m+1))/((x-1)(m-1)) = (x)/(m) are equal, then what is the value of m ?

The HCF of (a -1) (a^(3) + m) and (a +1) (a^(3) -n) and (a +1) (a^(2) -n) " is " a^(2) -1 , then the value of m and n are ______
