Answer:
Yes, you can find the cube root of a negative number. The answer will be negative!
Step-by-step explanation:
Example: Find the cube root of -27
We know that a cube root is a number multiplied by itself 3 times (NOT MEANING THE NUMBER TIMES 3)
For example, The cube root of 27 positive is 3 because 3 x 3 x 3 = 27
But if we are using a negative number: It is really different because we got to know the rules.
The setup: -3 x -3 x -3 = -27
If we started with -3 x -3 first we know that a negative times a negative equals positive so the answer will be 9 positive, then we have this equation left:
9 x -3 = -27
The rule with this is a number times a negative is negative, so the answer of the question "Find the cube root of -27 is -3"
12x8=96
4x4=16
96-16=80
answer:80cm squared
<h3>Given</h3>
- 40% of work week is 16 hours
<h3>Find</h3>
<h3>Solution</h3>
Write the given information as an equation.
... 0.40 × (work week) = 16 hours
Divide by the factor you don't want (0.40).
... (work week) = (16/0.40) hours
... work week = 40 hours
_____
40% means 40/100 (forty hundredths) or 0.40 (forty hundredths). (The % symbol is a shorthand way to write /100.)
