Evaluate
y2×8y
Multiply the terms with the same base by adding their exponents
y2+1×8
Add the numbers
y3×8
Use the commutative property to reorder the terms
8y3
8y3−9=0
Move the constant to the right-hand side and change its sign
8y3=0+9
Removing 0 doesn't change the value,so remove it from the expression
8y3=9
Divide both sides
88y3=89
Divide the numbers
y3=89
Take the 3-th root on both sides of the equation
3y3=389
