Answer

3√10

Explain

There are no steps or operations between the square roots, they can be simplified as a sequence of operations. Begin by simplifying √160, √90 and √40 separately:<br /><br />√160 converts into 4√10<br />√90 on its converts into 3√10<br />√40 on its own becomes 2√10.<br /><br />Then substitute it back into their original expression, therefore the results of this problem operation ↓:<br /><br />4√10-3√10+2√10 = 3√10
