Answer 2

Let the given equation be x.

Given,

$\sf{100 \times \dfrac{\sqrt{6^2+5^2}-\sqrt{5^2+4^2}}{\sqrt{5^2+4^2}}}$

$\sf{\implies x=100 \times \dfrac{\sqrt{6^2+5^2}-\sqrt{5^2+4^2}}{\sqrt{5^2+4^2}}}$

As we know the values,

• 6² = 36
• 5² = 25
• 4² = 16

Applying the values to the equation:

$\sf{\implies x=100 \times \dfrac{\sqrt{36+25}-\sqrt{25+16}}{\sqrt{25+16}}}$

$\sf{\implies x=100 \times \dfrac{\sqrt{61}-\sqrt{41}}{\sqrt{41}}}$

As we know the values,

• √61 = 7.81
• √41 = 6.40

$\sf{\implies x=100 \times \dfrac{7.81-6.40}{6.40}}$

$\sf{\implies x=100 \times \dfrac{1.41}{6.40}}$

$\sf{\implies x=100 \times 0.2203125}$

$\sf{\implies x=22.03125}$

$\huge{\boxed{\bold{\sf{\therefore x=22.03125}}}}$
