Final answer:
To simplify 52 * 54, we multiply the two numbers together.
Step-by-step explanation:
Multiplication is a mathematical operation that combines two or more numbers to calculate their product. It is one of the basic arithmetic operations, along with addition, subtraction, and division. In multiplication, the numbers being multiplied are called factors, and the result is called the product.
To simplify 52 * 54, we multiply the two numbers together. Using the properties of multiplication, we multiply the units digit first: 2 * 4 = 8. Then we multiply the tens digit: 5 * 4 = 20. Placing the units digit as the rightmost digit and carrying the tens digit, we get the final result: 2808. Therefore, the answer is d. 58.
