Question

A/a-c при а=корень из 8, с= корень из 2

Answer 1

√8/(√8-√2)=2√2/(2√2-√2)=2√2/√2=2

Answer 2

$\frac{a}{a - c}$
$\frac{ \sqrt{8} }{ \sqrt{8} - \sqrt{2} } = \frac{ \sqrt{8} }{2 \sqrt{2} - \sqrt{2} } = \frac{ \sqrt{8} }{ \sqrt{2} } = \sqrt{ \frac{8}{2} } = \sqrt{4} = 2$

Answer 3

To evaluate the expression A/a-c when a = √8 and c = √2, we need to substitute these values into the expression and perform the arithmetic operations.

Given: a = √8 c = √2

Now, let's calculate A/a-c:

A/a-c = A / (√8) - (√2)

To proceed further, we need more information about the value of A or the relationship between A, a, and c. As it stands, we can't determine the exact value of the expression without additional context. If you provide the value of A or any relevant equations involving A, we can help you compute the result.
