If the cost,in dollars, of a box of my favorite cereal is the same as the number of different values

Question:

If the cost,in dollars, of a box of my favorite cereal is the same as the number of different values of x which satisfy ( x square minus nine ) to the power of three equal to zero, then a box of this cereal costs how much ?

Answers

If the cost,in dollars, of a box of my favorite cereal is the same as the number of different values of x which satisfy ( x square minus nine ) to the power of three equal to zero, then a box of this cereal costs how much ? ------------------------ (x^2 - 9)^3 = 0 x^2 - 9 = 0 x = $3.

X^6-729=0 x=$2.08.

Since {{{(x^2-9)^3=0}}}, then there will be 3 SAME equations that equal 0 And so, just one of these 3 equations should be evaluated to find the different values of x Now, since {{{x^2-9=0}}} gives us x-values of + 3 or - 3, which are 2 VALUES, then the cost of the box of cereal is $2..
