Integer a > 1 ✱ Decimal b < 0

On this page, let's make the a in "a ✱ b" an integer > 1 and the b < 0.

Let's try out some variables for a using the formula a ^ (a ^ (b - 1)). Let's let b go from -1 to 0 in 0.25 steps.

Let's let a = 2.

2 ✱ -1.00 = 2 ^ (2 ^ (-1.00 - 1)) = 2 ^ (2 ^ (-2.00)) = 2 ^ 0.2500000 ≈ 1.1892071
2 ✱ -0.75 = 2 ^ (2 ^ (-0.75 - 1)) = 2 ^ (2 ^ (-1.75)) ≈ 2 ^ 0.2973017 ≈ 1.2288439
2 ✱ -0.50 = 2 ^ (2 ^ (-0.50 - 1)) = 2 ^ (2 ^ (-1.50)) ≈ 2 ^ 0.3535533 ≈ 1.2777036
2 ✱ -0.25 = 2 ^ (2 ^ (-0.25 - 1)) = 2 ^ (2 ^ (-1.25)) ≈ 2 ^ 0.4204482 ≈ 1.3383432
2 ✱ 0.00 = 2 ^ (2 ^ ( 0.00 - 1)) = 2 ^ (2 ^ (-1.00)) = 2 ^ 0.5000000 ≈ 1.4142135

2 ✱ -1.00 is the fourth root of 2 and 2 ✱ 0.00 is the square root of 2.

Let's let a = 4.

4 ✱ -1.00 = 4 ^ (4 ^ (-1.00 - 1)) = 4 ^ (4 ^ (-2.00)) = 4 ^ 0.0625000 ≈ 1.0905077
4 ✱ -0.75 = 4 ^ (4 ^ (-0.75 - 1)) = 4 ^ (4 ^ (-1.75)) ≈ 4 ^ 0.0883883 ≈ 1.1303555
4 ✱ -0.50 = 4 ^ (4 ^ (-0.50 - 1)) = 4 ^ (4 ^ (-1.50)) ≈ 4 ^ 0.1250000 ≈ 1.1892071
4 ✱ -0.25 = 4 ^ (4 ^ (-0.25 - 1)) = 4 ^ (4 ^ (-1.25)) ≈ 4 ^ 0.1767766 ≈ 1.2777035
4 ✱ 0.00 = 4 ^ (4 ^ ( 0.00 - 1)) = 4 ^ (4 ^ (-1.00)) = 4 ^ 0.2500000 ≈ 1.4142135

4 ✱ 0.00 = 2 ✱ 0.00 and 4 ✱ -0.50 = 2 ✱ -1.00.

Let's let a = 2 and b go from -2 to 0 in 0.25 steps.

2 ✱ -2.00 = 2 ^ (2 ^ (-2.00 - 1)) = 2 ^ (2 ^ (-3.00)) = 2 ^ 0.1250000 ≈ 1.0905077
2 ✱ -1.75 = 2 ^ (2 ^ (-1.75 - 1)) = 2 ^ (2 ^ (-2.75)) ≈ 2 ^ 0.1486508 ≈ 1.1085378
2 ✱ -1.50 = 2 ^ (2 ^ (-1.50 - 1)) = 2 ^ (2 ^ (-2.50)) ≈ 2 ^ 0.1767766 ≈ 1.1303555
2 ✱ -1.25 = 2 ^ (2 ^ (-1.25 - 1)) = 2 ^ (2 ^ (-2.25)) ≈ 2 ^ 0.2102241 ≈ 1.1568678
2 ✱ -1.00 = 2 ^ (2 ^ (-1.00 - 1)) = 2 ^ (2 ^ (-2.00)) = 2 ^ 0.2500000 ≈ 1.1892071
2 ✱ -0.75 = 2 ^ (2 ^ (-0.75 - 1)) = 2 ^ (2 ^ (-1.75)) ≈ 2 ^ 0.2973017 ≈ 1.2288439
2 ✱ -0.50 = 2 ^ (2 ^ (-0.50 - 1)) = 2 ^ (2 ^ (-1.50)) ≈ 2 ^ 0.3535533 ≈ 1.2777036
2 ✱ -0.25 = 2 ^ (2 ^ (-0.25 - 1)) = 2 ^ (2 ^ (-1.25)) ≈ 2 ^ 0.4204482 ≈ 1.3383432
2 ✱ 0.00 = 2 ^ (2 ^ ( 0.00 - 1)) = 2 ^ (2 ^ (-1.00)) = 2 ^ 0.5000000 ≈ 1.4142135

As the value of b gets smaller and smaller, the answer gets closer and closer to 1, but only a negative infinity for the value of b would make the answer be 1.
