Evaluate

Solution
Given: `5^-1 xx 3^0 + 25^(1/2)`
Step-wise calculation:
1. Evaluate each part:
`5^-1 = 1/5`
30 = 1 ...(Any non-zero number raised to 0 is 1)
`25^(1/2) = sqrt(25)`
`25^(1/2) = 5`
2. Substitute the values back:
`1/5 xx 1 + 5`
3. Multiply and add:
`1/5 + 5 = 1/5 + 25/5`
`1/5 + 5 = (1 + 25)/5`
`1/5 + 5 = 26/5`
