Answer 1

You should add your exponents first and then multiply the leading integers, and then put the numbers into scientific notation (x*10^y) where x is less than 10.

Answer 2

I'll help you
\[(3\times10^{2}) \times (5\times10^{5}) = (3\times5)\times(10^{2+5}) = 15\times10^{7} = 1.5 \times10^{8}\]

Answer 3

thank you sooooooooooooo much
