NQ= 2×5 =10
Using Pythagoras theoram,
PQ²+NP²=NQ²
4²+ NP²= 10²
NP²= 100-16
NP²= 84
NP =√84
<h3>
NP=2√21 = 9.2</h3>
2.32x10^8. I'm in Honors Chemistry in high school, I just inputted this into a calculator which is easy. Otherwise you can just take them out of scientific notation and into standard form which is this:
(160000000)(5800000)/4000000=232000000. And then convert it back.
