(5sqrt((3125)/(243)))^(-1)= _____

Divide 10y^(2)z^(3) by 5y^(2)z

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 ?

If ((243)^((n)/(5))3^(2n+1))/(9^(n)3^(n-1))=x, then the value of x is

If A=({:(2,3,10),(4,-6,5),(6,9,-20):}) find A^(-1) . Using A^(-1) solve the system of equations. (2)/(x)+(3)/(y)+(10)/(z)=2,(4)/(x)-(6)/(y)+(5)/(z)=5,(6)/(x)+(9)/(y)+(20)/(z)=-4
