2^a + 3^a + 4^a = 89

1^a + 1^a + 1^a = 89

3^a = 89

a = 86

an I do it right

**peter**, Thursday, December 19, 2013 at 12:42pmIf # (a,b,c,d)means you raise b,c and d to the power of d and then take the sum of the resulting values, and # (2,3,4,d)=89,then d=?

2^d + 3^d + 4^d = 89

1^d + 1^d + 1^d = 89

3^d = 89

d = 86
