Question 186806


{{{sqrt(128)-sqrt(75)-sqrt(98)}}} Start with the given expression



{{{8*sqrt(2)-sqrt(75)-sqrt(98)}}} Simplify {{{sqrt(128)}}} to get {{{8*sqrt(2)}}}. Note: If you need help with simplifying square roots, check out this <a href=http://www.algebra.com/algebra/homework/Radicals/simplifying-square-roots.solver> solver</a>.



{{{8*sqrt(2)-5*sqrt(3)-sqrt(98)}}} Simplify {{{sqrt(75)}}} to get {{{5*sqrt(3)}}}.



{{{8*sqrt(2)-5*sqrt(3)-7*sqrt(2)}}} Simplify {{{sqrt(98)}}} to get {{{7*sqrt(2)}}}.



{{{(8*sqrt(2)-7*sqrt(2))-5*sqrt(3)}}} Group like terms.



{{{sqrt(2)-5*sqrt(3)}}} Combine like terms.



So {{{sqrt(128)-sqrt(75)-sqrt(98)=sqrt(2)-5*sqrt(3)}}}
