LHS has either too few or too many digits, unless d=4.
Then abc in the range 178-316 raised to the 4th power has 10 digits.
However a=1 makes the leading digit of the result =1, and a is not represented in the result.
There's no c in the result so c<>0,1,5,6.
At this point I started checking values and quickly found abc=207, d=4, efghbghfbe=1836036801, so 5 and 9 are absent.
Time is short so I didn't check further.
