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

Hi there! 252 miles per gallon would be 252 miles/8 gallons. The GCF of 252 and 8 is 4 so we are going to divide by 4. 252÷4=63 and 8÷4=2. In this case, we have a fraction of 63/2.
The examples of 50,000 written as an exponent are as follows (but not limited to):
500 * 10^2
50 * 10^3
5 * 10^4
0,5 * 10^5
Doublecheck (optional):
500 * 10^2 = 500 * 100 = 50,000
50 * 10^3 = 50 * 1000 = 50,000
5 * 10^4 = 5 * 10000 = 50,000
0,5 * 10^5 = 0,5 * 100000 = 50,000
