What is the simplified form of the following expression

Question

3[42-2-(102-92)]

Answer 1

To simplify the expression, we first need to perform the operations inside the innermost parentheses:

3[42-2-(102-92)] = 3[42-2-10]

Next, we simplify the subtraction inside the brackets:

3[30-10]

Now, we perform the subtraction inside the brackets:

3[20]

Finally, we multiply the number outside the brackets by the number inside the brackets:

3 * 20 = 60

Therefore, the simplified form of the expression 3[42-2-(102-92)] is 60.
