Afellow calculus enthusiast was working through some practice problems. they come to you asking if the following problem is correct: ∫ 3x 2 + 1 2x dx = x 3 + x x 2 + c determine if they are correct. explain how you know if they are correct without integrating the function (i.e. find another method using calculus)

111/125 (reduced to simplest form)

Step-by-step explanation:

Step 1: Write down the percent divided by 100 like this:

88.8% = 88.8/100

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As we have 1 digit after the decimal point, we multiply both numerator and denominator by 10, or, simply shift 1 decimal place to the right. So,

88.8/100 = (88.8 x 10)/(100 x 10) = 888/1000.

Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(888,1000) = 8. So,

(888÷8)/(1000÷8) = 111/125 when reduced to the simplest form.
