Question 251304
(-6/y)^3 = (-6)^3/y^3 = -126/y^3


this is because (a/b)^3 = a^3/b^3


let a = 5 and let b = 9


(a/b)^3 = (5/9)^3 = .171467764 (use your calculator to solve)


(a/b)^3 = a^3/b^3 = 5^3/9^3 = 125/729 = .171467764


they are equivalent.


what you were asking me to solve is not an equation, but an expression.


(-6/y)^3 is an expression.


when you make it equal to something, then the whole thing becomes an equation.


example:


(-6/y)^3 = 99635


now you have an equation.


the expression on the left side of the equal sign equals the expression on the right side of the equal sign.
