Answer:
Step-by-step explanation:
Our expression is: .
Let's focus on the cube root of 81 first. What's the prime factorisation of 81? It's simply: 3 * 3 * 3 * 3, or . Put this in for 81:
We know that the cube root of 3 cubed will cancel out to become 3, but the cube root of 3 cannot be further simplified, so we keep that. Our outcome is then:
Now, let's multiply this by 1/3, as shown in the original problem:
Thus, the answer is .

Answer:
4√73
Step-by-step explanation:
x^2= 12^2 + 32^2
x^2= 144+ 1024
x^2=1168
x= 4√73
The area of a circle is given by
whereas the circumference is given by
If we want these two values to be (numerically) the same we have to set and solve for the radius:
So, one (trivial) solution is . A circle with radius 0 is just a point, and so both area and circumference are zero.
The other solution is . In fact, you have
