Rachel states that -5.5 is an integer because it is negative. Is she correct Why or why not?
Correct
9x = 243 ln(9x) = ln(243) xln(9) = ln(243) x = ln(243)/ln(9) x = 2.5 NB this works with log10 too. NBB if you don't have a calculator, this kinda question will only have easy values of x like integer values or 0.5, so its always worth chucking numbers in.
The correct answer is 64
Since the numerator and denominator of the fraction share no common positive integer factors other than 1, the proper fraction 130/243 is already expressed in its simplest form.
That is correct. There are none.
That's correct - there is none. For any integer, you can subtract one to get an even smaller integer.
The least common multiple (LCM) is often also called the lowest common multiple or smallest common multiple. Keep in mind that these different terms all refer to the same thing: the smallest positive integer which is a multiple of two or more numbers.The least common multiple of 81 and 243 is 243.
1
That is correct.
