Answer 2

Well remember that if you do anything to both sides of an equality it stays the same. So for instance if 2=2, you can multiply or subtract the same number from both sides!

So if you have \[45=\sqrt{30d}\] you can then square both sides and divide both sides by 30 after that to find out what d is.
