Question

I need help since I don't understand this well.

Answer 1

Answer:

9x10^16

Step-by-step explanation:

Since your exponent 16 is same all you have to do is, Add 2+7 and write the same 10^16

So your answer will be 9x10^16

Hope this helps!

Answer 2

Answer:

$9$ × $10^{32}$

All you have to do is simplify!

Step-by-step explanation:

$(2$ × $10^{16}) + (7$ × $10^{16}) = 9$ × $10^{32}$

All you have to do to simplify is add the 2 whole numbers together (2+7 = 9) and add the powers together (16 + 16 = 32, so the exponent would be $10^{32}$).

I hope this helps!
