2√8+3√8

Answer 1

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.

Answer 2

but thats not working

Answer 3

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.

Answer 4

√31 + √31

Answer 5

To simplify the expression √31 + √31, we can combine the like terms:

√31 + √31 = 2√31

Therefore, √31 + √31 simplifies to 2√31.

Answer 6

Subtract 7√5−4√5 what is The difference is .

Answer 7

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.
