To add 3\u221221−√ + 7\u221221−√, we can combine the terms with the same radical. This gives us (3 + 7) √21 = 10 √21.
To add 19−√ + 19, we simply add the numbers outside the radical. This gives us 2√19.
To add 22−√3 + 32−√ + 22−√, we can also combine the terms with the same radical. This gives us (22 + 3 + 2) √3 = 27 √3.
To subtract 8\u221223−√−23−√, we can simply subtract the numbers outside the radical. This gives us -15√3.
The difference in miles run each day is found by subtracting the distance run on Tuesday from the distance run on Monday.
So, the difference is 76 – 56 = 20 miles.
Add 3 21−−√ + 7 21−−√ .
Add 19−−√ + 19
Add 22−−√3 + 322−−√ + 22−−√
Subtract 8 23−−√−23−−√.
