How I would I solve this equation

Do you mean:
\[(\sqrt{2})(3\sqrt{2})\]

OpenStudy (jozelynw):
what is different between them?

OpenStudy (jhannybean):
\[\large \sqrt{2} \cdot \sqrt[3]{2} = 2^{1/2} \cdot 2^{1/3} = 2^{(1/2) + (1/3)}\]

OpenStudy (jhannybean):
Well, think about your exponent rule. \(\large \sqrt[n]{x^m} \implies x^{m/n}\)

Then when you have something like \(\sqrt{2} \cdot 3\sqrt{2}\) , you can easily factor out the common term, \(\sqrt{2}\) and add the multipliers. \[\sqrt{2} \cdot 3\sqrt{2} = \sqrt{2}(1+3) = 4\sqrt{2}\]

5/6 maybe
11 years ago
OpenStudy (jhannybean):
\[\frac{1}{2} + \frac{1}{3} = \frac{3}{6} + \frac{2}{6} = \frac{ 2+3}{6} = \frac{5}{6}\]

ok so whats next?

OpenStudy (jhannybean):
Therefore you can write the fraction exponent as: \(2^{5/6} \iff \sqrt[6]{2^5}\)

Ok thank you I get it.
