Answer:

Step-by-step explanation:
Hi!
So, a radical is basically a fractional power.
Square roots are numbers to the 1/2.
For example, the square root of 4 is just
, or 2.
So for cube root, the 1/2 changes to a 1/3.
This can then be rewritten as 
or 
When measuring a penny, using the millimeter measurement would be more accurate then using inches or centimeters.

Answer:
{-1, -8}
Step-by-step explanation:
Please enclose "1 - 3x" inside parentheses so the reader will know that you want the square root of all of "1 - 3x".
Squaring both sides of the given equation, we get:
1 - 3x = x^2 + 6x + 9, or x^2 + 6x + 8 + 3x, or
x^2 + 9x + 8 = 0. Factoring, we get: (x + 8)(x + 1) = 0, so that the solutions are {-1, -8}.
48.5 is the answer.
Reason- an expression is an equation without an equal sign and this expression is saying 53.5 - 5.
