percentages?

A fraction times 100% = the percentage. Just don't cross the % sign out.

May be you mean (5 x 10 - 1)²?

(5 x 10 - 1)²

=\(49^2\)

= 2401

Solve for x:
4 x^3 = 24

 

Divide both sides by 4:
x^3 = 6

 

Taking cube roots gives 6^(1/3) times the third roots of unity:
Answer: |  x = -(-6)^(1/3)    or    x = 6^(1/3)    or    x = (-1)^(2/3) 6^(1/3)

Isn't the answers third roots of unity: \((-1)^{\frac{1}{3}}(6)^{\frac{1}{3}}\), \(\sqrt[3]{6}= 6^{\frac{1}{3}}\), \((-1)^{\frac{2}{3}}(6)^{\frac{1}{3}}\)

4.65705e+14 = 465705000000000

465705000000000 minutes = 7761750000000 hours.

465705000000000 seconds = 129362500000 hours.

465705000000000 milliseconds = 1293625000 hours.

465705000000000 microseconds=1293.625 hours = 1293 hours 37 minutes 30 seconds

Hi Guest, I am Max :D

Please post the question to let us indicator whether it's quadratic or cubic. Thanks.

\(k+np^2\)

=\(0.5+(-3)\times(-2)^2\)

=\(0.5+(-3)\times4\)

=\(0.5-12\)

=\(-11.5\)

1/2 (a)(b) sin(c) where abc are sides of the triangle and angle c is the angle between a and b.

 Yes this is correct but just adding that C is the included angle. 

Wow I am so embarrassed I did the wrong maths 

\(\frac{2}{\frac{1}{5}}=2\times 5=10\)
