Question

Subtract 7 √5 - 4 √5

Answer 1

Subtract √29 - √29

Answer 2

To subtract these two numbers, 7√5 and 4√5, we can combine like terms. Since both terms have a coefficient of √5, we can simply subtract the coefficients.

7√5 - 4√5 = (7 - 4)√5 = 3√5

Therefore, the solution is 3√5.

Answer 3

To subtract √29 - √29, we can combine the like terms, which in this case is √29.

Since both terms have the same radical (√29), subtracting them will result in the coefficient being zero.

So, √29 - √29 = 0

Therefore, the solution is 0.
