Answer:
1.02×10¹ = 10.2
Step-by-step explanation:
We have given a number in scientific notation as follows 1.02×10¹
We need to convert it into standard notation.
1 is in ones place, 0 is in tenths place and 2 is in hundredths place.
![1.02\times 10^1=\dfrac{102}{100}\times 10\\\\=\dfrac{102}{10}\\\\=10.2](https://tex.z-dn.net/?f=1.02%5Ctimes%2010%5E1%3D%5Cdfrac%7B102%7D%7B100%7D%5Ctimes%2010%5C%5C%5C%5C%3D%5Cdfrac%7B102%7D%7B10%7D%5C%5C%5C%5C%3D10.2)
So, the standard notation of 1.02×10¹ is 10.2
Subtract 4 from 15 to get 11.
=x+11
