Explanation:
I am not sure I can read the original expression right, the picture is too blurry for the small digits.
is it 3^(5/5) ?
or rather 3^(5/6) ?
in any case, you should know that a number written like this always has the structure
a^(b/c)
so,
a = 3
b = 5 (or whatever is the numerator or top of the fraction)
c = 5 (or whatever is the denominator or bottom of the fraction).
the denominator of a fraction in an exponent gives us the grade of root to be taken.
the numerator gives us the power of the base number.
and if the exponent is negative it would mean that the whole thing is a 1/... fraction.
like 3^-2 means 1/3².
