When simplifying
, you can use the laws of exponents. First, combine the exponents in the numerator:
. Now you have
, which simplifies to
. Since any non-zero number raised to the power of zero equals 1, the final answer is
.
Now, let’s look at some useful exponent rules! Exponents can make calculations easier. Remember that multiplying numbers with the same base means adding the exponents (as we did with
and
). For division, subtract the exponents. Knowing these rules can simplify even complex calculations in no time!
When working with exponents, a common mistake is miscalculating when combining or subtracting exponents. Always double-check your operations to ensure you don’t mix up addition with multiplication. For instance,
definitely combines through addition, but confusion can arise if the operations aren’t clear. Keeping track of your work can save time and frustration!
