User: (x exponent 3) exponent 5

Weegy: The exponent of a number says how many times to use the number in a multiplication.
In 82 the "2" says to use 8 twice in a multiplication, [
so 82 = 8 ? 8 = 64
Exponents are also called Powers or Indices.
In words: 82 could be called "8 to the power 2" or "8 to the second power", or simply "8 squared"
Some more examples:
Example: 53 = 5 ? 5 ? 5 = 125
In words: 53 could be called "5 to the third power", "5 to the power 3" or simply "5 cubed"
Example: 24 = 2 ? 2 ? 2 ? 2 = 16
In words: 24 could be called "2 to the fourth power" or "2 to the power 4" or simply "2 to the 4th"
Exponents make it easier to write and use many multiplications
Example: 96 is easier to write and read than 9 ? 9 ? 9 ? 9 ? 9 ? 9 ] awbi371|Points 110|
