```python
from langchain.agents import load_tools
from langchain.agents import initialize_agent
from langchain.agents import AgentType
from langchain.llms import OpenAI
```

First, let's load the language model we're going to use to control the agent.


```python
llm = OpenAI(temperature=0)
```

Next, let's load some tools to use. Note that the `llm-math` tool uses an LLM, so we need to pass that in.


```python
tools = load_tools(["serpapi", "llm-math"], llm=llm)
```

Finally, let's initialize an agent with the tools, the language model, and the type of agent we want to use.


```python
agent = initialize_agent(tools, llm, agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION, verbose=True)
```

Now let's test it out!


```python
agent.run("Who is Leo DiCaprio's girlfriend? What is her current age raised to the 0.43 power?")
```

     I need to find out who Leo DiCaprio's girlfriend is and then calculate her age raised to the 0.43 power.
    Action: Search
    Action Input: "Leo DiCaprio girlfriend"
    Observation: Camila Morrone
    Thought: I need to find out Camila Morrone's age
    Action: Search
    Action Input: "Camila Morrone age"
    Observation: 25 years
    Thought: I need to calculate 25 raised to the 0.43 power
    Action: Calculator
    Action Input: 25^0.43
    Observation: Answer: 3.991298452658078
    
    Thought: I now know the final answer
    Final Answer: Camila Morrone is Leo DiCaprio's girlfriend and her current age raised to the 0.43 power is 3.991298452658078.
