1/4√28 find the rationalization denominator

Answer»

Answer:

Step-by-step EXPLANATION:

\frac{1}{4\sqrt{28} }

= \frac{1}{4\sqrt{28} }   ×  \frac{4\sqrt{28} }{4\sqrt{28} }    

\frac{1*4\sqrt{28} }{4^{2} (\sqrt{28} )^{2} \\} }  the SQUARE root and the square gets cancelled

= \frac{4\sqrt{28} }{<klux>16</klux>(28)\\} }   (now we've GOT to multiply 28 with 16)

= \frac{4\sqrt{28} }{448}    ( the 4 and 448 gets cancelled )  

= \frac{\sqrt{28} }{<klux>112</klux>}

if more simplification needed

\frac{\sqrt{28} }{112}  ( \sqrt{28} can also be written as \sqrt{4 * 7} )

= \frac{\sqrt{4 * 7} }{112}

= \frac{2\sqrt{7} }{112}   ( 2 and 112 gets cancelled)

= \frac{\sqrt{7} }{56}
