Answer: #1: 4[tex]\\\sqrt{2}[/tex]
#2: -6x^7
Step-by-step explanation:
#1 simplify the radical expression
10[tex]\sqrt{2}[/tex] - [tex]\sqrt{72}[/tex]
10[tex]\sqrt{2}[/tex] - 6[tex]\sqrt{2\\}[/tex]
collect like terms
Solution: 4[tex]\sqrt{2}[/tex]
#2 combine like terms
-3*2 = -6 then add the 5 and 2
