Scientific notation, also called pattern or notation in exponential form, is a way of writing numbers that accommodate values too large (100000000000) or small (0.00000000001) to be written in a conventional manner.
The use of this notation is based on powers of 104
Example:
Big numbers:

Small numbers:

However, in areas such as physics and chemistry, scientific notation is important to make approximations such as:
mass of a proton
mass of an electron and others.
Answer:
54 inches
Step-by-step explanation:
At least pet snake is 42 inches long and Royals pet snake is 8 feet long.How many inches longer is Royals snake
Step 1
We would be converting the length of the Royal's pet snake to inches
1 foot = 12 inches
8 feet = x
Cross Multiply
x = 8 × 12 inches
x = 96 inches
Step 2
How many inches longer is Royal's snake?
This is calculated by subtracting the length of the Royal's pet snake from the least length
= 96 inches - 42 inches
= 54 inches
Therefore, the Royal's snake is 54 inches longer
19.37cm is 74.5% of 26cm so we then we need to take away 19.37 from 26cm that leaves us with 6.63
hope i helped was quite hard just remember the way i did it
