You only wrote one option, but luckily, those two fractions ARE equivalent!
We know that because if you multiply the denominator AND numerator by 4, you get 16/20.
ANSWER: To determine if all three of those fractions have the same decimal equivalent, we simply divide the numerator by the denominator. Fractions mean division! So for the first one 21/3 That's 21 divided by 3. That's 7!
Answer:
C. The square root of a number, positive or negative, is always positive. However, the cube of a negative number is negative.
Step-by-step explanation:
Of the choices offered, the one shown above is the only one that remotely makes any sense. Its description of square roots is erroneous, however.
The square root of a number n is the solution to the equation ...
x² = n
The function f(x) = x² has a range that only includes non-negative numbers, so the square root of a negative number does not exist. (Your answer choice says it is positive. It is actually non-existent among real numbers.)
On the other hand, the cube root of a number n is the solution to the equation ...
x³ = n
Since f(x) = x³ has a range that includes all real numbers, the cube root of n exists for all real numbers. (It is negative for negative values of n.)
