Question

I need help in my homework here it is Solve the equation for x. x3 = 729

Answer 1

Firstly the coefficient, or the number next to the variable, which is x, goes before it. So instead of x3, it's 3x.

So, to solve to find what x is, you need to divide by 3 on both sides of the equal sign.

3x=729

Dividing by 3 on the left cancels out the 3, leaving just the x.

Dividing the other side gets you what x equals.

x= 243

Answer 2

x3=729

729/3= 243

x=243
