We are going to find for the unit form of the
given equation which is (2 tens 1 one) x 10.
First, let’s define what unit form in place value is.
Unit form means the value of each given digit depending on where it is placed.
=> We were given (2 tens 1 one) which can be written as 21
=> 2 is in the tens place and 1 is in the ones place.
=> so now, where going to multiply 21 by 10
=> 21 x 10
=> 210
