This video shows the method to simplify expressions with different exponents. The video starts with the explanation of 16 raised to the power 1/4. This can be solved by taking the nth or the 4th root of 16 where n stands for the denominator of the fraction. Then the video explains 8 raised to power 4/3. This can be solved in two ways. First one involves taking the cube root of 8 and raising it to the power of 4. The second method involves converting 8 into 2 raised to the power 3 and taking the product of 3 and 4/3 to get 2 raised to 4 which turns out to be 16. The third example involves a negative power of a number. The negative power is changed to positive by taking the reciprocal of the number and removing the negative sign in the power. Rest rules are same as in previous examples.
