Sure, let's write the numbers in standard form step-by-step.
1. For the number [tex]\( 70000000 + 100000 + 90000 + 80 \)[/tex]:
- Start with [tex]\( 70000000 \)[/tex].
- Add [tex]\( 100000 \)[/tex].
- To this sum, add [tex]\( 90000 \)[/tex].
- Finally, add [tex]\( 80 \)[/tex].
Combining these:
[tex]\[
70000000 + 100000 + 90000 + 80 = 70190080
\][/tex]
Therefore, the answer in standard form is [tex]\( \boxed{70190080} \)[/tex].
2. For the number expressed in words: Four billion, seventy-five million, six hundred thousand, two hundred:
- Four billion is [tex]\( 4,000,000,000 \)[/tex].
- Seventy-five million is [tex]\( 75,000,000 \)[/tex].
- Six hundred thousand is [tex]\( 600,000 \)[/tex].
- Two hundred is [tex]\( 200 \)[/tex].
Combining these:
[tex]\[
4,000,000,000 + 75,000,000 + 600,000 + 200 = 4075600200
\][/tex]
Therefore, the answer in standard form is [tex]\( \boxed{4075600200} \)[/tex].
