Darnell earned $10 each week for 10 weeks walking a neighbor's dog. How much did he earn?

Write the amount Darnell earned using exponential notation for $10 each week for 10 weeks.

Which of the following, when written in standard form, is equal to the standard form of 2 2nd power?

Exponential Notation

Exponential notation represents repeated multiplication of a number.
Example: 10x10x10x10x10 is written as 10 to the 5th power.
Other examples include:
- 7x7x7 as 7 to the 3rd power
- 13x13x13x13x13x13 as 13 to the 6th power
- 6x6x6x6 as 6 to the 4th power

Expanded Form

Expanded form expresses a number's exponentiation as repeated multiplication.
Key examples:
- 10 to the 5th power is expressed as 10x10x10x10x10.
- 35 squared (35^2) is represented as 35x35.
- 4 to the 3rd power is shown as 4x4x4.

Standard Form

Standard form is the simplified numerical value of an exponentiation.
Important conversions:
- 5 to the 4th power equals 625.
- 10 to the 3rd power equals 1,000.
- 4x4x4 equals 64.
- 12 squared is equal to 144.

Common Errors

8 to the 2nd power may seem to equal 16, but it actually equals 64 since it is calculated as 8x8.

Square Roots

To find a number that equals 81 when squared, the answer is 9 (since 9x9=81).

Profit Calculation

Darnell's earnings formula involves weekly pay for hours worked:
- Earning $10 each week for 10 weeks results in a total of $100.
- This can also be expressed using exponential notation as 10 to the 2nd power (10^2).

Standard Form Comparison

The question of equivalence is also addressed for expressions like 2 to the 2nd power, which equals 4 when converted to standard form.
