1. Earl puts $1,000 in an investment, which compounds annually at 5% every year. How much will be the investment worth after six years?
2. Find x if 7^4x+10=7^2x
1. There's definitely a formula for this, but I don't know it. So I just did 1000 * 1.05, and then timesed that by 1.05, and I just did that 6 times and I got 1340.09564063.
2. \(\frac {-5}{1176}\) I think
1.
1000 ( 1.05)^6 ≈ $1340.10
Thank you so much!
