is -1 and + 1
Indices are expressed using exponents and bases. Some of the useful laws of indices are:

Given the expression;

This can also be expressed as:
![b^2=\frac{1}{b^{10}}\\b^2 \times b^{10} =1\\b^{2+10} =1\\b^{12}=1\\b=\pm\sqrt[12]{1}\\b=\pm1](https://tex.z-dn.net/?f=b%5E2%3D%5Cfrac%7B1%7D%7Bb%5E%7B10%7D%7D%5C%5Cb%5E2%20%5Ctimes%20b%5E%7B10%7D%20%3D1%5C%5Cb%5E%7B2%2B10%7D%20%3D1%5C%5Cb%5E%7B12%7D%3D1%5C%5Cb%3D%5Cpm%5Csqrt%5B12%5D%7B1%7D%5C%5Cb%3D%5Cpm1)
Hence the value of b from the given indices is -1 and + 1
