Answer 1

Answer:

the second power of a number is called exponent

Answer 2

Exponent is the second power of a number

Explanation:

• The exponent of a number says how many times to use the number in a multiplication.
• In 8^2 the "2" says to use 8 twice in a multiplication,  so 8^2 = 8 × 8 = 64.
• In words: 8^2 could be called "8 to the power 2" or "8 to the second power", or simply "8 squared".
• Exponents are also called Powers or Indices.

Example: 5^3 = 5 × 5 × 5 = 125

In words: 5^3 could be called "5 to the third power", "5 to the power 3" or simply "5 cubed"

Example: 2^4 = 2 × 2 × 2 × 2 = 16

In words: 2^4 could be called "2 to the fourth power" or "2 to the power 4" or simply "2 to the 4th"
