You can put this solution on YOUR website!
2%5E4%2Asqrt%282x%29+%2B+6%5E4%2Asqrt%282x%29
Since 2%5E4+=+16 and 6%5E4+=+1296 this becomes:
16%2Asqrt%282x%29%2B1296%2Asqrt%282x%29
These are like terms so we can add them:
1312%2Asqrt%282x%29

Since there is not any of the provided answers there must be something wrong with the problem or with how you posted it. (I suspect the later. Are those really square roots?)
