Evaluating Exponential Expressions
Now, in order to evaluate expressions without a calculator, we first need to understand the
different exponents that are available. There are three primary exponents- the square root,
the cube root, and the fifth root- and each has a different meaning. For example, the
square root of 3 means that the number is multiplied by itself three times and then divided
by 2. This is why 3 squared is 9. The cube root of 3 means that the number is multiplied
by itself three times and then divided by 6. This is why 3 cubed is 9. The fifth root of 3
means that the number is multiplied by itself five times and then divided by 2. This is
why 5 cubed is 25. Now, in order to evaluate expressions without a calculator, we first

cubed is 9. The fifth root of 3 means that the number is multiplied by itself five times and
then divided by 2. This is why 5 cubed is 25. However, there are also other exponents
available which we may not be familiar with. For example, consider the expression 1 over
5 cubed- this expression has an exponent of 5. However, what does this actually mean?
Well, if we take 1 and multiply it by 5 cubed, we will get 50 (5 x 5). However, if we take
5 and multiply it by 1, we will get 5 (1 x 5). Therefore, 1 over 5 cubed means "multiply 1
by 50 and divide it by 5," or "round up to the nearest whole number." So, it's important to
be aware of all of the different exponents that are available so that we can evaluate
expressions accurately without resorting to a calculator.
