9.434 X 10^66

Step-by-step explanation:

2.34 X 10^65 + 9.2 X 10^66 (First, you have to manipulate the exponents to bring them to the same index, i. e. the same power)

We can say that 2.34 X 10^65 = 0.234 X 10^66

Now that the indexes are equivalent, we can proceed to add the two bases together.

0.234 X 10^66 + 9.2 X 10^66

= (0.234 + 9.2) X 10^66

= 9.434 X 10^66
