Answer 1

b = -14.

• A number's square root is a value that, when multiplied by itself, yields the original number. The other way to square an integer is to find its square root. Squares and square roots are hence linked ideas.
• Assuming that x is the square root of y, the equation would be written as x=√y or as x² = y. The radical symbol for the number's root is "" in this instance. The square of the positive number is represented by multiplying it by itself. The original number is obtained by taking the square root of the square of a positive number.

Here, according to the given information, it is given that,

$\frac{\sqrt{5}+\sqrt{3} }{\sqrt{5}-\sqrt{3} }$

$=\frac{\sqrt{5}+\sqrt{3} }{\sqrt{5}-\sqrt{3} }.\frac{\sqrt{5}+\sqrt{3}}{\sqrt{5}+\sqrt{3}}\\=\frac{28+2\sqrt{15} }{2}\\=14+\sqrt{15}$

Now, this is equal to -b+$\sqrt{15}$.

Hence, b = -14.
