Question

1. write your own numerical expression that equals 20 using at least three different operations (addition, multiplication, exponents, etc.).

Explanation:

Step1: Choose operations and numbers

Let's use exponentiation, multiplication, and addition. Let's take \(2^2\) (exponent), multiply by 4 (multiplication), and add 4 (addition).

Step2: Construct the expression

First, calculate \(2^2 = 4\). Then multiply by 4: \(4\times4 = 16\). Then add 4: \(16 + 4 = 20\). So the expression is \(2^2\times4 + 4\).

Answer:

\(2^2\times4 + 4\) (Other valid expressions like \(3^2 + 5\times1 + 6\) are also acceptable)
