  1. If   √0.04 × 0.4 × a = 0.004 × 0.4 × √b,   value of  
    a
    		   is
    b
    1. 16 × 10−3
    2. 16 × 10−4
    3. 16 × 10−5
    4. 16 × 10−6
Correct Option: C

√0.04 × 0.4 × a
= 0.004 × 0.4 × √b
Squaring both sides,
= 0.004 × 0.4 × 0.004 × 0.4 × b

⇒ 
a
 =
0.004 × 0.004 × 0.4 × 0.4
 = 0.00016
b0.04 × 0.4

=
16
 × 16 × 10−5
