Power (^)

Exponentiation (SymPy, WMA)

Power[a, b]

a ^ b

represents a raised to the power of b.

• • 4 ^ (1/2)

• • 4 ^ (1/3)

• • 3^123

• • (y ^ 2) ^ (1/2)

• • (y ^ 2) ^ 3

• • Plot[Evaluate[Table[x^y, {y, 1, 5}]], {x, -1.5, 1.5}, AspectRatio -> 1]

Use a decimal point to force numeric evaluation:

• • 4.0 ^ (1/3)

Power has default value 1 for its second argument:

• • DefaultValues[Power]

• • a /. x_ ^ n_. :> {x, n}

Power can be used with complex numbers:

• • (1.5 + 1.0 I) ^ 3.5

• • (1.5 + 1.0 I) ^ (3.5 + 1.5 I)
