So, there’s a few problems here.
Firstly, is the w meant to represent the second number as an exponent? because if so, the correct symbol is (^) and it should look like (40^4) and (8^6). Or is the w meant to be a variable and you need to simplify (40*w*4) and (8*w*6).
Secondly, if you did mean you need (40^4) and (8^6) to be simplified, the only way something can be simplified without being solved is if the equation has a variable(letter) in it such as x or y.
To simplify something means combining the terms until there is nothing left you are able to do. So solving the problems would be simplifying them since they have no variables
If you did mean (40^4) and (8^6) to be simplified, the answers would be
40^4= 2,560,000
8^6=262,144
I hope this information was helpful in anyway, I would be happy to help you if you could clarify for me what you want simplified by leaving a comment on this answer
