Explanation

Given:

(1+x)(1+x2)(1+x4)(1+x8)(1−x),

$$$$(1+x)(1+x2)(1+x4)(1+x8)(1−x)

This is a well-known identity in algebra that builds up as a geometric progression product:

Identity:

(1−x)(1+x)(1+x^2)(1+x^4)(1+x^8)=1−x^16

$$$$(1−x)(1+x)(1+x2)(1+x4)(1+x8)=1−x16

So,

(1+x)(1+x^2)(1+x^4)(1+x^8)(1−x)=1−x^16

$$$$(1+x)(1+x2)(1+x4)(1+x8)(1−x)=1−x16

Explanation

 24 is split into two parts such that 7 times the first plus 5 times the second is 146.

Let the first part be 

x, then the second is 

7x+5(24−x)=146

7x+120−5x=146

2x=26⇒x=13

The "Edit, Clear" command in spreadsheet software (like Microsoft Excel) allows you to remove different elements from selected cells, such as:

• Contents (values/data)

• Formats (cell formatting)

• Comments/Notes

However, it does not delete the cells themselves—it only clears their contents or attributes.

Explanation

 To copy the contents of a cell using drag and drop, you need to hold down the Ctrl key while dragging the cell

Explanation

The function key to quickly navigate to a specific cell in MS Excel is F5 or Ctrl+G.

These keys open the "Go To" dialog box, where you can enter the cell reference (e.g., B3) and press Enter to jump to that cell

Explanation

To find the sum of the four numbers, multiply the average by the total count of numbers:

Average = 24

Total count = 4

Sum = Average × Total count

Sum = 24 × 4

Sum = 96

Explanation

Derived from: computare

Means: “to calculate”, “to count”, “to sum up” or “to think together”.
