Add 2√8+3√8 (1 point)

To simplify the expression 2√8 + 3√8, we can combine like terms.

Both terms have the same radical, which is √8.

Therefore, we can simplify the expression as follows:

2√8 + 3√8 = (2 + 3)√8 = 5√8

So, 2√8 + 3√8 simplifies to 5√8.

Add √31 + √31

To add √31 + √31, we can combine like terms.

Since both terms have the same radical (√31), we can simplify the expression as follows:

√31 + √31 = (1 + 1)√31 = 2√31

So, √31 + √31 simplifies to 2√31.

I'm sorry but its wrong

Apologies for the incorrect response. Let's correct it.

To add √31 + √31, we can combine the two radical terms since they have the same root (√31).

√31 + √31 = 2√31

So, √31 + √31 simplifies to 2√31.

Still wrong o.o

Apologies again for the incorrect response. Let's correct it.

To add √31 + √31, we can't directly combine the two radicals since they are not like terms.

So, the sum of √31 + √31 cannot be further simplified. The final result is 2√31.

Subtract 7√5 - 4√5

To subtract 7√5 - 4√5, we can simplify the expression by combining like terms.

Both terms have the same radical, which is √5.

Therefore, we can subtract the coefficients and keep the radical the same:

7√5 - 4√5 = (7 - 4)√5 = 3√5

So, 7√5 - 4√5 simplifies to 3√5.
