Question

if 2a+1/2a=8,find
4a 4 a square + 1 by 4 square ​

Answer 1

Step-by-step explanation:

$2a + \frac{1}{2a} = 8$

${(2a + \frac{1}{2a}) }^{2} = {(8)}^{2}$

$4{a}^{2} + \frac{1}{4 {a}^{2} } + 2 = 64$

$4 {a}^{2} + \frac{1}{4 {a}^{2} } = 62$

Therefore, it is your answer.

Answer 2

Answer:

4a² + (1/4a² ) = (2a + (1/2a))² – 2.2a (1/2a)

(2a + (1/2a))² – 2 = (8)² – 2 = 64 – 2 = 62
