Answer 3

It seems like you're trying to solve a series of mathematical expressions. However, the question is not clear and the expressions are not formatted properly, making it difficult to understand what you're asking.

Here's a general approach to solving mathematical expressions:

1. Simplify the expressions: This involves combining like terms and simplifying the expression as much as possible. For example, if you have an expression like `7200 + 90`, you can simplify it to `7290`.

2. Use algebraic methods to solve: If the expression is an equation, you can use algebraic methods such as factoring, completing the square, or the quadratic formula to solve for the variable. For example, if you have an equation like `x^2 - 5x + 6 = 0`, you can factor it to `(x - 2)(x - 3) = 0`, which gives you the solutions `x = 2` and `x = 3`.

3. Use a calculator or mathematical software: If the expression is complex, you can use a calculator or mathematical software to solve it. For example, if you have an expression like `sqrt(49)`, you can use a calculator to find that the answer is `7`.

If you can provide more details or clarify your question, I'd be happy to help further.
