Answer:
Step-by-step explanation: From the above question, we have been given some hints to assist in the number interpretation.
Answers are:
-4.99
1.9435
3.25E4
1.56e-9
The above selected numbers have been selected using the hints below:
You cannot have commas in numbers.
You cannot have a space in a number.
You cannot substitute the letter O for zero or the letter l for 1.
You cannot include the units or a dollar sign in the number.
You can have the sign of the number, + or -.
You can do this by finding a number close to it, and then finding out how to do it.
For example with 63(square root sign), find out what is close to it.
7x7=49 while 8x8=64
Because of this, we now know that it is between 7 and 8 but is also really close to 8.
Our number could be 7.9
Hope this helped!!!
