What is the coefficient of xy4 in the expansion of (2x + y)5?

The coefficient of in the expension of   is 10.

Step-by-step explanation:

Given , we have to find the coefficient of in the expension of  .

Here, a = 2x and b = y ,  

Substitute above, we get,

Using

Adding all terms, we get,

On evaluating , we get,

Thus, the coefficient of in the expension of   is 10.

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
