Dierdra saw a pole that was supported by a wire as shown.
She calculated that the wire was the square root of 1,625 feet long. Between which two numbers is the value of square root of 1,625 located?

when you have that bar ... over some numbers, then it means that number keeps repeating. eg

such repeating numbers are rational numbers ... just multiply it by 100 or (in your case 10) and subtract from the original number.
