Nine times the difference of a number cubed and three. (B)
Always check the prime factorization for the terms under the radical sign so that you know which perfect squares can be removed...
√26
√(2*13) Since both term are primes to the first power, there is nothing to move out from under the radical and it is already in its simplest form.
Answer:
(x+2)/(x+3)
Step-by-step explanation:
because same denominator(x+2) and numerator(x+2) can be removed.
