To raise a number X to the power of Y in Go, use the `Pow(x, y float64)`

function from the `math`

package.

```
package main
import (
"fmt"
"math"
)
func main() {
res := math.Pow(2, 7) // 2^7
fmt.Println(res)
}
```

Output:

```
128
```

To calculate the power of 10 up to the Y exponent in Go, use the `math.Pow10(n int)`

function.

```
package main
import (
"fmt"
"math"
)
func main() {
res := math.Pow10(3) // 10^3
fmt.Println(res)
}
```

Output:

```
1000
```
