The answer is 12n = 78. Why? Well, the product of a number and 12 can be written as 12n because it is a coefficient which includes a variable for an unknown value. Since there is an unknown value (that’s called “a number” in this expression), 12n is the standard form of this representation. Since the product of a number and 12 is 78, we can use an equal sign followed by a 78 to show that 12n is equal to 78. If you need to better understand this, let me know and I will gladly assist you.
