sqrt%2850%29+=+sqrt%2825%2A2%29


sqrt%2850%29+=+sqrt%2825%29%2Asqrt%282%29


sqrt%2850%29+=+5%2Asqrt%282%29


-------------------------------------------------------


sqrt%288%29+=+sqrt%284%2A2%29


sqrt%288%29+=+sqrt%284%29%2Asqrt%282%29


sqrt%288%29+=+2%2Asqrt%282%29


-------------------------------------------------------


From the work above, we will use the idea that


sqrt%2850%29+=+5%2Asqrt%282%29


sqrt%288%29+=+2%2Asqrt%282%29


to simplify


-------------------------------------------------------


2%2Asqrt%2850%29+%2B+12%2Asqrt%288%29


2%2A5%2Asqrt%282%29+%2B+12%2Asqrt%288%29


2%2A5%2Asqrt%282%29+%2B+12%2A2%2Asqrt%282%29


10%2Asqrt%282%29+%2B+24%2Asqrt%282%29


%2810+%2B+24%29%2Asqrt%282%29


34%2Asqrt%282%29


=======================================================


So 2%2Asqrt%2850%29+%2B+12%2Asqrt%288%29 simplifies to 34%2Asqrt%282%29
