WebCase 1: both a and b are positive, Case 2 either a OR b is negative (not both), meaning one is negative, one positive. Case 3 BOTH a AND b are negative. 1) Both a and b are positive. Ex. SQT [4 * 1] = SQT [4] * SQT [1] SQT [4*1] = SQT [4]=2 (Principal square root only) SQT [4]*SQT [1]=2*1=2 2=2 => Success 2) a is positive and b is negative. Ex. WebAlthough even roots of negative numbers cannot be solved with just real numbers, odd roots are possible. For example: (-3) (-3) (-3)=cbrt (-27) Even though you are multiplying a negative number, it is possible to obtain a negative answer because you are multiplying it with itself an odd number of times. Let's walk through it a little more slowly:
