Subtract the numbers
−75w3
50w4−75w3
50w4−75w3=0
Factor the expression
25w3(2w−3)=0
Divide both sides
w3(2w−3)=0
Separate the equation into 2 possible cases
w3=02w−3=0
The only way a power can be 0 is when the base equals 0
w=02w−3=0
Solve the equation
More Steps

Evaluate
2w−3=0
Move the constant to the right-hand side and change its sign
2w=0+3
Removing 0 doesn't change the value,so remove it from the expression
2w=3
Divide both sides
22w=23
Divide the numbers
w=23
w=0w=23
Solution
w1=0,w2=23
