Question

( quad sqrt{3+5 a}=4 )
( =3+5 a=16 )
( begin{aligned}=1 & sqrt{a}=13 therefore a=169 &= 3 y^{2}=2 &=sqrt{frac{7}{5}}=frac{sqrt{2}}{sqrt{5}} end{aligned} )

# Oral Assignment 1. If 3+ Va = 4, then a is Sol. a = 169. 2. The value of y for which sy? - t = 0, is Sol. y = Tri 3. Square numbers can have only number zeroes at the end. Sol. Even
