Explain the importance of exponents and power.


Importance of exponents and powers:

  • Exponents or powers are important in math because they permit us to abbreviate or write in short something that would otherwise be really long and difficult to write.

For example,

If we want to express the product of 5 multiplied by itself 7 times,

without exponents we'd only be able to write that as,

$5 \times 5 \times 5 \times 5 \times 5 \times 5 \times 5$

That is 5 multiplied by itself 7 times in a row.

This is not so easy to write if the number of times it is multiplied is really big, say 20 times or 50 times and  so on

In exponent form $5 \times 5 \times 5 \times 5 \times 5 \times 5 \times 5 = 5^7$ which is short and easy to write.
