the square root of five a over 18 so this can be rewritten as this is equal to the square root of five egg while over the square root of 18. But 18 is well nine times to right, and nine is a perfect square. So the squared nine times two is to squirt at nine times the square to to, and it's got a nine history. So this is equal to the square root of five a. Over Well, the square root of nine is reason that this squid of 18 is equal to three times the square root of two. So we have the square root of five a over three times the square to to all right thinking.
