Question

√[4+(81/400= (a/20) -1​

Answer 1

The correct question is:$\sqrt{[4+(81/400)]}$=(a/20)

Find the value of a.

Answer:

The required value of a is 41.

Step-by-step explanation:

Equation: In mathematics equation is a statement which represent two equal quantities.

Solution: Solution of an equation is that value which satisfy the given condition of an equation.

here,

$\sqrt{[4+(81/400)]}$=(a/20)

⇒$\sqrt{[4+0.2025]}$=(a/20)

⇒$\sqrt{4.2025}$=(a/20)

⇒2.05=(a/20)

⇒a=2.05×20   [multiplying 20 in both side of the equation]

⇒a=41

hence the solution of the equation is 41.

Answer 2

Answer:

The required value of a is 41.

Step-by-step explanation:

Equation: In mathematics equation is a statement which represent two equal quantities.

Solution: Solution of an equation is that value which satisfy the given condition of an equation.

here,

\sqrt{[4+(81/400)]}

[4+(81/400)]

=(a/20)

⇒\sqrt{[4+0.2025]}

[4+0.2025]

=(a/20)

⇒\sqrt{4.2025}

4.2025

=(a/20)

⇒2.05=(a/20)

⇒a=2.05×20 [multiplying 20 in both side of the equation]

⇒a=41

hence the solution of the equation is 41.
