1/3-2√3 rationing factor​

Answer»

Answer:

I don't know about this sum but you can solve this way

Since (3+10−5)(3+10+5)

 =(3+10)2−(5)2

 =3+10+2310−5=8+230

and , (8+230)(8−230)=82−(230)2

 =64−4×30=−56

Therefore,

 (3+10−5)(3+10+5)(8−230)

 =−56 which is a rational number

Hence, (3+10+5)(8−230) is a rationalizing factor of (3+10−5)
