A) (3)² = 3 × 3 and 10(8)² = 10 × 8 × 8
B) (3)² = 9 and 10(8)² = 640
For any number x, the square of the number denoted by (x)² is equal to 2 times x multiplied by itself or x*x.
Here, we are given two expressions- (3)² and 10(8)²
we need to write both of them in expanded form and then write their values.
Expanded form of (3)² is 3 × 3
The value of the expression (3)² will be-
(3)² = 3 × 3 = 9
Similarly, expanded form of 10(8)² is 10 × 8 × 8
The value of the expression 10(8)² will be-
10(8)² = 10 × 8 × 8 = 640

Solution
The given number is 32, 897
Here we need to round the thousand place.
Find the number in the thousands place.
We have 2 in the thousands place.
Look for digit which is right to 2.
We have 8, which is greater than 5, if we have the number greater than 5 we have to add 1 with thousands place and make the other numbers zeros.
Since we have 8 right to the number 2, so we add 1 with 2.
2 + 1 = 3
Now thousands place became 3 and make other digits zero.
32, 879 = 33, 000
The answer is 33,000
