How do i solve these kind of problems?
-�ã((7c)^2)
To solve problems like this, you need to simplify the given expression by following the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
Let's solve the problem step by step:
1. Start by evaluating the expression inside the innermost parentheses: (7c)^2.
- To square a term, raise it to the power of 2. In this case, it would be (7c)^2 = 49c^2.
2. Now substitute the simplified expression back into the original expression:
- The original expression -�ã((7c)^2) can be rewritten as -�ã(49c^2).
3. Finally, simplify the outermost set of parentheses:
- The square root of 49 is 7, so -�ã(49c^2) simplifies to -7c.
Hence, the solution to the problem -�ã((7c)^2) is -7c.
