2√8+3√8
To simplify the expression 2√8 + 3√8, we can combine like terms because both terms have the same radical (√8).
First, we perform the multiplication of the coefficient and the radical separately for each term:
2√8 = 2 * √(2*2*2) = 2 * 2√2 = 4√2
3√8 = 3 * √(2*2*2) = 3 * 2√2 = 6√2
Now we can simplify the expression by combining like terms:
4√2 + 6√2 = (4 + 6)√2 = 10√2
Therefore, 2√8 + 3√8 simplifies to 10√2.
but thats not working
Apologies for the mistake in my previous response. Let's try solving it again.
To simplify 2√8 + 3√8, we can combine the like terms:
2√8 + 3√8 = (2+3)√8
Now, let's simplify the coefficients:
2+3 = 5
Therefore, 2√8 + 3√8 simplifies to 5√8.
√31 + √31
To simplify the expression √31 + √31, we can combine the like terms:
√31 + √31 = 2√31
Therefore, √31 + √31 simplifies to 2√31.
Subtract 7√5−4√5 what is The difference is .
To subtract 7√5 - 4√5, we can combine like terms:
7√5 - 4√5 = (7 - 4)√5
Now, let's simplify the numerical coefficient:
7 - 4 = 3
Therefore, the difference of 7√5 - 4√5 is 3√5.
