SCHOLItTM. 



When fractional expo?ients of the powers of the scjne rovt 

 have hot the same denominator, they may be brought to a 

 common denominator, like vulgar fractions, and then their 

 numerators may be added, or subtracted, as before. 



Thus> the quotient of /7<:-|-^P divided by y/^-f-;?!'*^ is 



ac 



+^h ^=:ac'{'X\ 4 ±=:z ac*^x\ . 



Note 2. Surd quantities under the same radical sign 

 are divided, one by the other, like rational quantities, only 

 the quotient, if it do not become rational, must stand un- 

 der the same radical sign. 



Thus, the quotient of y/^i divided by ^3 is y/y. 



That of ^ab by ^a is ^L 



3 3 — 3 



That of ^i6c by ^2c is -y/8, 



That of v^^f by ^^H'' is i. 



Andthat of i2a'';^y|" by s^V;'^!'' is 4;^;;')" 



CASE II. 



When the divisor is a simple quantity and the dividend a com- 

 pound quantity. 



RULE. 



Divide every term of the dividend by the divisor, as in 

 the first case.
