Question

Can someone please help me on this question

Answer 1

A. The scientific notation for 50,000,000 is 5 x 10^7 (to the 7th power)

B. After squaring 50,000,000 you'll get 2500000000000000. In scientific notation, this is 2.5 x 10^15 (to the 15th power). 

C. I think what it's asking is how I solved part B... this could be wrong, double check it. I solved it by multiplying 50,000,000 x 50,000,000 and then converting the product into scientific notation. 

Hope this helps, if you have more questions, message me or comment under this post!
