Question

What are exponents and powers. (explain briefly)

Answer 1

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
In words: 82 could be called "8 to the power 2" or "8 to the second power", or simply "8 squared"

Exponents are also called Powers

Answer 2

Usually, a power is
represented with a
base number and an
exponent. The base
number tells what
number is being
multiplied. The exponent, a
small number written above
and to the right of the base
number, tells how many times
the base number is being
multiplied.
For example, “6 to the 5th
power” may be written as
“6 .” Here, the base number is
6 and the exponent is 5. This
means that 6 is being
multiplied by itself 5 times: 6 x
6 x 6 x 6 x 6
6 x 6 x 6 x 6 x 6 = 7,776 or 6
= 7,776
