Subtract two exponents with same base ... 9^9$, but I didn't know the rules for subtracting exponents with ...
Brother, I know you're smart enough that you know quadratic equations, Here in your question it is asked that : \exp(2x)-exp(x)=110 You can subsitute \exp(x)=u And by the knowledge of exponentials we know \exp(2x)= u^{2} which gives us : \u^{2}-u=110 then you can solve this equations easily then when you get to value of u, break u into \exp(x) and then you can take the logarithm and get the ...
A term like y−4 y − 4 is essentially saying 1 y4 1 y 4 in the denominator because a negative exponent is the opposite of a positive exponent and you use division. And so here you are dividing by y y four times. So if that's the case, you cross multiply: 1 y4 y4 1 1 y 4 y 4 1 on bottom and then of course to keep balance, you multiply y4 1 y ...
What I'm wondering is about the 2^4 - 2^3. I know this is is 2^3 because 2^3 is the value multiplied by 2 to get 2^4, which means I'm subtracting the same value I'm adding when going from 2^3 to 2^4 from 2^3 and thereby going back to 2^3.
I am entirely new to this subject and am already lost. The problem is Five x Ten to the power of Negative Two, + Four x Ten to the power of Negative Three. I was told that I have to make the exponents the same, and to do that I had to move one of the decimals, so I made Four x Ten to negative Two into 40 x Ten to negative Two.

2. My understanding is that the exponent n + 1 n + 1 means that xn+1 = x ⋅xn x n + 1 = x ⋅ x n. Your understanding is correct, and you can apply it to the problem at hand by remembering that when an exponent, say n n, of an expression is in the denominator of a fraction, it can be written as an expression raised to the −n − n power.
0. I'm not sure if you mean 3x+4 − 5(3x) = 684 3 x + 4 − 5 (3 x) = 684 or 3x + 4 − 5(3x) = 684 3 x + 4 − 5 (3 x) = 684. If you mean the first, then rewrite 3x+4 3 x + 4 as 3x ⋅34 3 x ⋅ 3 4 and then factor 3x 3 x out. If you mean the second way, subtract 4 4 from each side and then factor out 3x 3 x. Hope this helps.
