We want to evaluate the expression 7 to the negative 5 times 7 square divided by 7 to the negative 2nd, all raise to the power of negative 1.
00:11
In order to answer a problem like this, we need to have a fundamental understanding of the rules associated with exponential and logarithmic functions.
00:20
So i have made note of all the important exponent of spone root rules you would use to solve a problem like this.
00:25
We won't need to use all of these rules now, but they're important, so i recommend writing them down.
00:30
Rule a notably connects the exponential function to the square root.
00:33
Function, which is important because parts b through g or rules b through g here are all for exponents.
00:40
But because of rule a, we can also use rules b through g for roots as well...
