Rounding to the nearest ten means to get the ones place and, if it's 4 or less, turn it to zero. If the ones place is 5 or more, turn the ones place to 0 and add 1 to the tens place.
This number has an ones place of 4 or less, so we turn the ones place to 0. We then get 71,290, so the answer is 71,290
