The original expression is 3835. In order to do this, we can use the fact that the base of both exponents are the same and then simplify.

 

3835 Since the bases are identical, just add the exponents together. In general, abac=ab+c
3835=38+5=33 A number to a negative exponent is the same as the inverse of a number to the same positive exponent. ab=1ab
33=133=1333=127 This is your answer.
