Answer 2

To find the value of the expression, simply follow the order of operations (PEMDAS/BODMAS) which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

1. Start with the parentheses: -3 * (1/4) - 36 * (1/4)^2

2. Evaluate the expressions inside the parentheses: -3 * (1/4) = -3/4 (1/4)^2 = (1/4) * (1/4) = 1/16

3. Replace the values in the expression: -3/4 - 36 * (1/16)

4. Next, perform the multiplications: -3/4 - 36 * (1/16) = -3/4 - 36/16

5. Find a common denominator (in this case, 16) and convert the fractions: -3/4 = -12/16

6. Subtract the fractions: -12/16 - 36/16 = -48/16

7. Simplify the fraction (if possible): -48/16 = -3

So, the value of the expression is -3.
