Question

2a+1/3a=6,then what's the value of 4a²+1/9a² ​

Answer 1

Answer:

37/2304

Step-by-step explanation:

2a+1/3a=6

=>2a+1=18a ( by cross multiplication )

=> 1 =18a - 2a

=> 1 = 16a

=> a = 1/16

Putting the value of a in this equation

=>4a^2+1/9a^2

=>4 × ( 1/16)^2 + 1/9×(1/16)^2

=>4× 1/256 + 1/9×256

=>4/256 + 1/2304

=>36+1/2304

=>37/2304

Answer 2

104/3

Step-by-step explanation:

first both the squares can be written as

(2a)^2+(1/3a)^2

then evaluate this as a^2+b^2=(a+b)^2-2*a*b

the put the value whic is given and the other a in the right will devide each other
