Question

4. (1) ( frac{sqrt{72}}{sqrt{32} times sqrt{147} times sqrt{252}} )
( begin{aligned} &=sqrt{frac{72 times 363 times 175}{32 times 147 times 252}} &=sqrt{frac{9 times 121 times 25}{4 times 49 times 36}} &=frac{3 times 11 times 5}{2 times 7 times 6}=frac{55}{28} end{aligned} )

# 172 x 7363 x V175 4. Simplify 147 1252
