Answer:
10
Step-by-step explanation:
Half of 10 is 5. 5+5 is 10
Answer: The equation is 24 + x = 56
Step-by-step explanation: x would be 32, but the set up would be 24 + x = 56, since both of their cookies equal 56.
(Im also assuming you meant 24 and not 242424, same with 56.
Answer:
20
Step-by-step explanation:
you add 15 and 5
Answer:
3.
Step-by-step explanation:
When dealing with radicals and exponents, one must realize that fractional exponents deals directly with radicals. In that sense, sqrt(x) = x^1/2
Now, how to go about doing this:
In a fractional exponent, the numerator represents the actual exponent of the number. So, for x^2/3, the x is being squared.
For the denominator, that deals with the radical. The index, to be exact. The index describes what KIND of radical (or root) is being taken: square, cube, fourth, fifth, and so on. So, for our example x^2/3, x is squared, and that quantity is under a cube root (or a radical with a 3). Here are some more examples to help you understand a bit more:
x^6/5 = Fifth root of x^6
x^3/1 = x^3
^^^Exponential fractions still follow the same rules of simplifying, so...
x^2/4 = x^1/2 = sqrt(x)
Hope this helps!
