Math Formulas
Math formulas are expressions that have been created after several decades of research that help to solve questions quickly. It is easy to perform simple arithmetic calculations such as addition, subtraction, and so on. However, when it comes to algebraic expressions, geometry, and other topics you need mathematical formulas to simplify the process of reaching the answer and saving time in the process. At Cuemath you will not only find formulas for every topic but will also get an idea of how that equation was developed. Thus, you will not have to memorize formulas, as you understand the concept behind them.
Use these formulas to solve problems creatively and you will automatically see an improvement in your mathematical skills. Given below is the list of formulas alphabetically arranged for your convenience. Hence, you can easily find formulas that need to be revised or require to be referenced.
The links to the list of math formulas available on different topics have been arranged alphabetically for your convenience. So pick a topic and start learning!

Answer:
The second bubble
Explanation
You need to make your exponents equal the other side so to do this;
Distribute the 3 in the exponent "3(x-2)"
Which is 3x-6
And since multiplying exponents adds them, you need a -6 to make the two equal.
So your exponent should equal -6 to make that statement true
