Simplify: b. 4√10-√10

4 sqrt 10 - 1 sqrt 10 = 3 sqrt 10

thanx damon :D

What is the coefficient of the c-term of the algebraic expression 14a - 72r - c - 34d?

i don't even know the half

To simplify the expression 4√10 - √10, we can combine the terms that have the same square root.

Since both terms have the square root of 10, we can combine them by subtracting the coefficients (the numbers in front of the square root) while keeping the square root intact.

So, 4√10 - √10 = (4 - 1)√10 = 3√10.

Therefore, the simplified form of the expression 4√10 - √10 is 3√10.
