First, note that 7^2 equals 7 * 7 = 49. Now, we have:
49 =
In order to solve for x, we need to use logarithm, which basically "gets rid of" the exponent. What we need to do is take the of each side. Notice that the base of the logarithm is 12. This is because we want to cancel out the exponent base of 12 on the right side:
Answer: The word phrase for this expression is the last option, "The sum of the quotient of d and 5 and 2." d is being divided by 5, so we would use "quotient of d and 5" for that part, and then we would add the "sum" because d/5 is being added to 2.
