Answer:

You haven't provided expressions, so I can work out the problem for you. When we divide fractions, remember always "keep, switch, flip!" That's what we're gonna do here. We keep the 2/5, switch the sign to multiplication, and flip the 7/8 to 8/7. Therefore, we have 2/5*8/7. That gives us 16/35. Hope this helps!

Square root of 648.7209 by division method
SpyIntel [72]

Answer:

25.47

Step-by-step explanation:

This root can be rewritten as:

\sqrt{\frac{6487209}{10000} }

\sqrt{\frac{6487209}{100^{2}} }

\frac{1}{100}\cdot \sqrt{6487209}

Since 6487209 is a multple of 3, the expression can be rearranged as follows:

\frac{1}{100}\cdot \sqrt{3\times 2162403}

2162403 is also a multiple of 3, then:

\frac{1}{100}\cdot \sqrt{3^{2}\times 720801}

\frac{3}{100}\cdot \sqrt{720801}

720801 is a multiple of 3, then:

\frac{3}{100}\cdot \sqrt{3\times 240267}

240267 is a multiple of 3, then:

\frac{3}{100}\times \sqrt{3^{2}\times 80089}

\frac{9}{100}\cdot \sqrt{80089}

80089 is a multiple of 283, then:

\frac{9}{100}\cdot \sqrt{283^{2}}

\frac{9\times 283}{100}

\frac{2547}{100}
