## Description{% #description %}

Simple operations such as `math.Pow` with a small number can be simplified. Simplification should be used when applicable.

## Non-Compliant Code Examples{% #non-compliant-code-examples %}

```go
func main () {
    foo := math.Pow(x, 0)
    foo := math.Pow(x, 1)
    foo := math.Pow(x, 2)
    foo := math.Pow(x, 3)
    foo := math.Pow(x, 4)
    foo := math.Pow(x, 010)
}
```

## Compliant Code Examples{% #compliant-code-examples %}

```go
func main () {
    foo := 1
    foo := x
    foo := x*x
    foo := x*x*x
    foo := math.Pow(x, 4)
    foo := math.Pow(x, 010)
}
```
