[00:00:00]This is really the key to uh solving this problem is understanding that 4 to the 1/2 is the same thing as the square root of 4.

[00:00:08]Okay, so hopefully you know what it means to take a uh base to a uh power of 1/2. In other words, when we have an exponent of 1/2, what does this mean?

[00:00:20]Well, it means taking the square root.

[00:00:23]All right, so for example, 4 to the 1/2 power is the same thing as the square root of 4. All right, so this right here in math is called a rational exponent, and you can write powers with rational exponents. See uh See here, 1/2 is a rational number, i.e. a fraction. So, you can write these as um some sort of radical, right? So, when you have a square root, technically there's a little two right here, but uh we never write this. But uh this is a big topic in math, and especially in algebra. All right, so this is really the key to uh solving this problem is understanding that 4 to the 1/2 is the same thing as the square root of 4.
