<div class="api-signature">

[`Tensor`](../Tensor.md) **`pow`**([`Tensor`](../Tensor.md) `input`, [`ScalarOrTensor`](../ScalarOrTensor.md) `exponent`)

</div>

Raises `input` to `exponent` elementwise: $a^{exponent}$. Broadcasts and promotes as [`add`](./add.md#add); a scalar `exponent` keeps its weak kind (an integer exponent with an integer base stays integral).

**Returns:** the broadcast-shaped powers at the promoted dtype.

**Throws**

- `ClikaRT::Error`: (`INVALID_ARGUMENT`) when the operand shapes are not broadcast-compatible.
