17 multiplied by 17 is equal to 289. This can be calculated by multiplying the two numbers together using the standard multiplication algorithm, where each digit in the top number is multiplied by each digit in the bottom number and the results are added together. In this case, 7 multiplied by 7 is 49, which is written as 9 in the ones place and the 4 is carried over to the tens place.
