if a = 1 , what is the value of – ( a ^ 2 + a ^ 3 + a ^ 4 + a ^ 5 + a ^ 6 ) ?
"if a = - 1 , then putting values in equation = - [ ( 1 ) ^ 2 + ( 1 ) ^ 3 + ( 1 ^ 4 ) + ( 1 ^ 5 ) + ( 1 ^ 6 ) ] = - [ 1 + 1 + 1 + 1 + 1 ] = - 5 answer = e = - 5"
negate(add(add(add(power(1, 2), power(1, 3)), power(1, 4)), power(1, 5)))
