Question

2 times 10 to the 16th plus 7 times 10 to the 16th in scientific notation

Answer 1

Answer:

The answer is  $9\times 10^{16}.$

Step-by-step explanation:

Given:

2 times 10 to the 16th plus 7 times 10 to the 16th in scientific notation.

Now, to solve in scientific notation.

So, we change into scientific notation:

2 times 10 to the 16th

$=2\times 10^{16}$

7 times 10 to the 16th

$=7\times 10^{16}$

Now, to add:

$2\times 10^{16}+7\times 10^{16}$

As, we see the powers are same so we add the numbers in this standard form:

$=(2+7)10^{16}$

$=9\times 10^{16}.$

Therefore, the answer is $9\times 10^{16}.$
