Question

CAN ANYONE PLEASE EXPLAIN THIS EXPONENTIAL FORM
SPECIALLY IN STEP 2

Answer 1

Answer:

We know the exponential law:

$\boxed { \pink { a^{m+n} = a^{m} \times a^{n} }}$

In second step , we can apply above law,

$\green { 3^{n+1} = 3^{n} \times 3^{1} \\= 3^{n} \times 3 }$

In third step , we take $\green { 3^{n}}$ common
