7^(-3) = 1/7^3 = 1/343
- 7^3 = - (7^3) = -343
As can be seen, the results are very different.
Answer:
5/3
Step-by-step explanation:
2x+3=5x-2
Subtract 2x from both sides
3=3x-2
Add 2
5=3x
Divide by three
5/3=x
Answer:
lhh
Step-by-step explanation:
Answer:
r = (3V/π)^1/3
Step-by-step explanation:
Given that :
Volume of a sphere = V = 4/3πr³
Dividing into 4
4/3 * 1/4 πr³ = 4/12πr³ = 1/3πr³
V = 1/3πr³
Cross multiply
3V = πr³
Divide both sides by π
3V/ π = πr³/ π
3V/ π = r³
Take the cube root of both sides
r = (3V/π)^1/3
