To simplify the expression 3√21 + 7√2, we cannot combine the two square root terms since they have different radicands (the numbers inside the square root symbols).
Therefore, the expression 3√21 + 7√2 cannot be simplified further.

i meant 3√21 + 7√21
If the expression is 3√21 + 7√21, we can combine the like terms since they have the same radicand, which is 21.
Thus, 3√21 + 7√21 can be simplified to (3 + 7)√21, which equals 10√21.
Thus, 3√21 + 7√21 can be simplified to (3 + 7)√21, which equals 10√21.
√19 + √19
To simplify the expression √19 + √19, we can combine the like terms since they have the same radicand, which is 19.
Thus, √19 + √19 can be simplified to (1 + 1)√19, which equals 2√19.
Thus, √19 + √19 can be simplified to (1 + 1)√19, which equals 2√19.
Add ^3√22 + 3√22 + √22
To combine the terms ^3√22 + 3√22 + √22, we can add the coefficients in front of the like terms.
The coefficients in front of √22 are 1, 3, and 1. Therefore, ^3√22 + 3√22 + √22 equals 1 + 3 + 1 = 5.
Thus, the expression ^3√22 + 3√22 + √22 simplifies to 5√22.
The coefficients in front of √22 are 1, 3, and 1. Therefore, ^3√22 + 3√22 + √22 equals 1 + 3 + 1 = 5.
Thus, the expression ^3√22 + 3√22 + √22 simplifies to 5√22.
8√23 - √23
To combine the terms 8√23 - √23, we can subtract the coefficients in front of the like terms.
The coefficients in front of √23 are 8 and 1. Therefore, 8√23 - √23 equals 8 - 1 = 7.
Thus, the expression 8√23 - √23 simplifies to 7√23.
The coefficients in front of √23 are 8 and 1. Therefore, 8√23 - √23 equals 8 - 1 = 7.
Thus, the expression 8√23 - √23 simplifies to 7√23.
