I say we take the log on both sides as step one.
Yes?
Country Boy said:The first thing I would do is start dividing 343 by 7! 343- 40(7)= 343- 280= 63= 9(7) so \(\displaystyle 343= 7(49)= 7(7)(7)= 7^3\). \(\displaystyle \sqrt{343}= 7^{3/2}\) so \(\displaystyle 7^{2n}= 7^{3/2}\) so \(\displaystyle 2n= 3/2\), n= 3/4.
No logarithms necessary!

Yes, factoring can be considered a skill. It involves the ability to break down a mathematical expression or equation into smaller parts in order to simplify or solve it.
Yes, factoring is an important skill to have in mathematics. It is often used in algebra, calculus, and other branches of math to solve equations and simplify expressions.
Being able to factor allows you to solve complex equations and simplify expressions, making math problems easier to understand and solve. It also helps to develop critical thinking and problem-solving skills.
Yes, factoring can be useful in real-life situations such as budgeting, calculating interest rates, and solving business problems. It can also be applied in fields such as engineering, physics, and computer science.
Practicing regularly and familiarizing yourself with different factoring techniques can help improve your factoring skills. You can also seek help from a tutor or use online resources to learn and practice factoring.
