If a , b , c , , x , y , z are 26 natural numbers, then the value of (x-a)(x-b)(x-c)ddot(x-y)(x-z) is (a) 0 (b) 1 (c) 13 (d) 26

If x^(y^(z))=1, y^(z^(x))=125 and Z^(y^(x))=243 (x,y and z are natural numbers), then what is the value of 9x+10y-18z ?

For oxyacid HClO_(x) , if x=y=z (x,y and z are natural numbers), then calculate the value of |x+y+z|. Where x=number of 'O' atoms y=total number of lone pairs at central atom z=total number of pi (pi) electrons in the oxyacid.

For oxyacid HClO_(x) , fi x=y=z (x,y and z are natural numbers), then calculate the value of |x+y+z|. Where x=number of 'O' atoms y=total number of ions pairs at central atom z=total number of pi (pi) electrons in the oxyacid.

If x,y,z,t are odd natural numbers such that x+y+z+w=20 then find the number of values of ordered quadruplet (x,y,z,t)

If a + x = b + y = c + z + 1 , where a, b,c,x,y,z are non polar distinct real numbers , then |(x, a+y,x + a),(y , b+y , y + b),(z,c+y, z+c)| is equal to :

If a^x=b, b^y=c,c^z=a then the value of xyz is

If x, y, z, t are odd natural numbers such that x + y + z +t=20 then find the number of values of ordered quadruplet (x, y, z, t).

If x, y, z, t are odd natural numbers such that x + y + z +w=20 then find the number of values of ordered quadruplet (x, y, z, t).
