Question
Which of the following functions in Excel is used to
combine data from multiple columns into one?Solution
The CONCATENATE function in Excel is used to combine (or join) values from multiple columns or cells into one. This function is particularly useful when you want to merge names, addresses, or other data spread across multiple columns into a single cell. For example, you can combine a first name in one column with a last name in another column into a full name in one cell. Option A is incorrect because VLOOKUP is used to search for a value in a table and return a related value from another column, not to combine data. Option C is incorrect because SUMIF is used to sum values that meet a specific condition, not to concatenate data. Option D is incorrect as a pivot table is used for summarizing data, not for combining data from different columns. Option E is incorrect because LEFT is a text function used to extract a specified number of characters from the left side of a string, not to combine columns.
If the sum of three numbers is zero, then which of the options below will always be equal to the value of the sum of the cubes of those numbers?
If a =
and ...- If [3a + (1/2a)] = 5, then find the value of [9a² + (1/4a²) - 6]
Suppose xy = -15 and (x² + y²) = 34, then determine the value of (x – y).
If (a + b) = 10 and ab = 21, find the value of (a² + b²).
If x = 21, then the value of x5 - 22x4 + 22x3 - 22x2 + 22x - 1 is
(x + 1)2 + (y – 3) 2 + (z + 5) 2 = 0, then find the value of 2x + 3y - z.
