Answer:
1. =CONCATENATE(" John"," ","Smith")
2. =(" John"&" "&"Smith")
Explanation:
Given
Two separate strings; "John" and "Smith"
Required
2 separate formulas to concatenate both strings to form " John Smith"
There are several ways to concatenate strings in Microsoft Office Excel; one of the methods is using the concatenate function while the another method is using the traditional & operator.
Using the concatenate function, the formula is as follows
=CONCATENATE(" John"," ","Smith")
This function will combine the " John", " " and "Smith" to give a new string " John Smith" (without the quotes).
Using the traditional & operator may be a little bit difficult (and not frequently used) but the formula is as follows;
=(" John"&" "&"Smith")
The result will be the same as (1) above
