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 

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

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

0.47+1.072 = 1.542

2 log x + log x = 2

3 log x = 2

log x = \(\frac{2}{3}\)

x = \(10^{\frac{2}{3}}\)=\(\sqrt[3]{100}\)

That's the same as CPhill's , and our guest's answer in #1

\(\frac{6}{sin M}= \frac{10}{sin72}\)

\(M=asin[6(\frac{sin72}{10})]\)

which is about 34.79 degrees

That's a misleading proof though.

You mean this: \((\frac{a^{10}}{3})(\frac{b^7}{3})\)

But I mean this: \((a^{\frac{10}{3}})(b^{\frac{7}{3}})\)

There are major differences between the 2 equations.

And I guess the asker means my equation because he said simplified radical form and that's a term for 'Law of Indices'.

HI!!!!!

1+5=6

And you don't need Einstein to answer your question.

those are these in my eyes.

pi is a Greek letter.

pi, mathematically, means the ratio of circumference to the diameter.

\(2\frac{2}{3}+1\frac{3}{4}=2\frac{8}{12}+1\frac{9}{12}=3\frac{17}{12}=4\frac{5}{12}\)

-(w-x)-(-x-w)

= x-w+x+w

= 2x

 #2 Omi67

x=10^(2/3)=4.6415888336127788924100763509194

2 log x + log x =2 Substitute

2 log(4.6415888336127788924100763509194) + log(4.6415888336127788924100763509194)=2

[2 x 2/3] + 2/3 =2

1 1/3 + 2/3 =2

what is 20 over 15?

Melody's answer poses another riddle...........what happened to all the water  in the "Great Flood" story in the Bible???.......where did it go ???

Omi67......you have made a slight error........

2log x    ≠  (log x)²

2log x   =  log x²   

20/15  =  4/3
