Subtract 7 √5 - 4 √5
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.
To subtract 7√5 - 4√5, we first need to simplify the expression. Since both terms have the same radical (√5), we can combine them by subtracting their coefficients.
The coefficients are 7 and 4, so subtracting them gives us 7 - 4 = 3. Therefore, the simplified expression is 3√5.
Subtract √29 - √29
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.
To subtract 7√5 - 4√5, you can follow these steps:
1. Start by identifying the terms that have the same radical (√5 in this case). In this expression, both terms have the radical √5.
2. Keep the positive term as it is (7√5) and change the sign (from positive to negative) of the second term (4√5).
3. Now, you can combine the coefficients (numbers in front of the radical) of the two terms. In this case, subtract 4 from 7 which is 3.
4. Finally, bring down the common radical (√5). The simplified expression becomes 3√5.
Therefore, 7√5 - 4√5 simplifies to 3√5.
