Final answer:
To simplify the expression 20 + 522, you square the 5 to get 25, multiply by 2 to get 50, and then add 20 to get the final answer of 70.
Step-by-step explanation:
The question involves simplifying a mathematical expression. To simplify 20 + 522, we must follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). Since there are no parentheses to consider, we start with the exponent.
You square the digit term in the usual way, which means 52 equals 5 times 5, giving us 25. So, 522 represents 2 times 25, which is 50. Now we can rewrite the expression as 20 + 50, which when combined equals 70.
Final Answer: 70
