Question 1041281: HI !
Could you please help me insolving this problem ?
First problem:
3rd power, square root 3x-8 = 1
root%283%2C3x-8%29=1
Second one is :
Square root x+4 = square root x-2
sqrt%28x%2B4%29=sqrt%28x-2%29

Thank you for your help.

You can put this solution on YOUR website!
root%283%2C3x-8%29=1=1
root%283%2C3x-8%29=1³=1³
3x-8=1
3x=9
x=3. ☺☺☺☺
sqrt%28x%2B4%29=sqrt%28x-2%29
sqrt%28x%2B4%29²=sqrt%28x-2%29²
x+4=x-2
4=-2
This equation has no solutions. ☺☺☺☺
