how do you solve for non-integer exponents.
for example, consider the following
1.5 to the power of .525
1.5^.525
show me some examples please. I'm pretty bad at math.
For that one especially I'd use technology. Let the calculator solve it.
There are some common exponents
$\displaystyle x^{0.5} = \sqrt{x}$
$\displaystyle x^{0.333...} = \sqrt[3]{x}$
$\displaystyle x^{1.5} = \sqrt{x^3}$
In general
$\displaystyle x^{\frac{a}{b}} = \sqrt[b]{x^a}$
like I said I'm bad at math, so I don't totally understand your response, however I followed your suggestion and allowed my Windows XP calculator to solve for it. The calculator includes a function key for solving problems like these. The key look like this:
x^y
I had to try a few time to learn how this key works. Took me a few tries.
I took my number "x" (which was 1.766) and multiplied it by my "y" value exponent (.526) using the calculator function key and it worked properly.
so it was something like this: 1.766 ^ .526 = 1.34
thanks for your help.
So let's use the example of $\displaystyle 4^{0.23}$
This could be written as $\displaystyle 4^{\frac{23}{100}}$
Using the: rule, we can state that
$\displaystyle 4^{\frac{23}{100}} = \sqrt[100]{4^{23}} $
Now let's look at the case of $\displaystyle 4^{1.23}$
Using the rule $\displaystyle (x^a)(x^b) = x^{a+b}$
$\displaystyle 4^{1.23} = (4^1)(4^{0.23})$
$\displaystyle = 4( \sqrt[100]{4^{23}}) $
I'm not sure how to simplify that further, I don't know if it can be.
