2. write your own numerical expression that equals 20 using at least three different operations (addition…

Explanation:

Step1: Choose operations and numbers

Let's use exponentiation (e.g., (2^2)), multiplication (e.g., (3\times)), and addition (e.g., (+)). We can start building the expression. Let's consider (2^2\times3 + 8).

Step2: Calculate each part

First, calculate the exponent: (2^2 = 4). Then, the multiplication: (4\times3 = 12). Then, the addition: (12 + 8 = 20). So the expression (2^2\times3 + 8) equals 20. (Another example: (3^2 + 5\times2 + 1), where (3^2=9), (5\times2 = 10), then (9 + 10+1=20))

Answer:

One possible numerical expression is (2^2\times3 + 8) (or (3^2 + 5\times2 + 1), etc.)
