Question

Number 30 pleaseeeee

Answer 1

2^40 since you are trying to find the product you would just add the exponents together

Answer 2

To multiply values with exponents we can sue the following rule (assuming both numbers are in the same base):

$a^{n} \times a^{m}=a^{(n+m)}$

In this case we have:

$2^{10} \times 2^{30}=2^{(10+30)}=2^{40}$
