What is 5+2 to the third power multiplied by 2 ?

5+(2^3)*2
5+8*2
5+16
21

So, the answer is 21

HOPE THIS HELPS :)

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
