Question

exponential rule for x^b + x^c =​

Answer 1

$\huge {\mathbb {\pink {ANSWER}}}$

The rule of exponents says that when the base of two terms are equal, the powers are also equal.

So, according to this, the answer to your question would be:

$\large {{x}^{b} + {x}^{c} }$

=⟩ $\large {b + c}$

Note:

If it would have been: $\large {{x}^{b} \times {x}^{c} }$

Then, it could have been written as $\large {x^{b+c}}$ and not only $\large {b + c}$.

You can add or subtract only when the bases are equal.
