Work out the value 125^(-2/3) (A* Exam Q)
Whenever you have a negative power always take the reciprocal or flip the base value i.e 125. So now it is 1/125 raised to the power of 2/3. By flipping it over the fractional index is no longer negative. So now it is (1/125)^2/3. Since '3' is the denominator of he fractional power, cube root (1/125), which comes to 1/5. Now square the fraction since '2' is the fractional numerator (1/5)^2= 1/25Final answer=1/25
