Question

if 4^x-1=16 and 9^y+2=729. find the value of y/x-x/y​

Answer 1

Answer:

Therefore, the required cube root of 15625 is 25. Note: Here, after prime factorisation, you will get prime factors. Now, to obtain the cube root, take the similar numbers in groups of three and one factor from each group should be taken and then multiply all such factors.
