Question

1/4√28 find the rationalization denominator

Answer 1

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

= $\frac{4\sqrt{28} }{16(28)\\} }$   (now we've got to multiply 28 with 16)

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

= $\frac{\sqrt{28} }{112}$

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)

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