WebMultiply/Divide radicals : If the indexes are the same write as one radical. Multiply ♦ 2x3y⋅4 8x5y2 ⇐ The indexes are the same “4”. So, write as one radical first. ♦ 4 2x3y⋅8x5y2 ⇐ Everything inside will multiply. Note: Remember your power rules. ♦ 44 2⋅8x3x5yy2 ⇒ 416x8y3 ⇒ Reduce ⇒ 2x2 y3 WebNote: The radical must be isolated on one side of the equal sign before you can square both side. Example: Solve 2 x−5+3=21 The radical is not isolated. 2 x−5+3−3= 21−3 ⇐ Subtract the three first from both sides. − = ⇐ 2 18 5 2 2 x Divide two on both sides. x−5=9 ⇐Now we can square both sides. ( − ) =( )2 ⇐ 2
