i translate this to read:
this is equivalent to which is equivalent to which is equivalent to which is equivalent to the fifth root of .
i confirmed by assigning the value of 7 to a and the value of 9 to b and evaluated the original expression and the final expression.
i got the original expression = 101.4016814
i got the final expression = 101.4016814
since the values are the same, i assumed that the solution is correct.
the basic concepts used are:
=
= = the b root of .
for example:
= = = 64.
since 2^2 = 4 and 4^3 = 64, this confirms the concept is correct.
also:
= = square root of = 4.
since 2^4 = 16 and the square root of 16 is equal to 4, this confirms the concept is correct.
