how can i simplify the root of 125 into the form "a root b" using a SHARP EL-531W scientific calculator?

Answer 1

I don't know about the calculator but 125 is the cube of 5 and so we can write cube root of 125 = 5 ( 5 X 5 = 25 and 25 X 5 = 125)

Answer 2

I don't think you can, you simply have to learn the method of breaking up the number underneath the square root into a number and a square number.

Root of 125... how is 125 made? Well.. 5 is a factor of 125, and 25 x 5 = 125. This gives you a number and one square number.

You simply square root the square number, and in this case, root of 25 becomes 5. This number goes infront of the root sign so the answer should be 5 root 5.

Hope this helps!

Answer 3

I don't think you can. You have to use your brain a bit.

Start with the 125 and divide it by each prime number until it will divide exactly.

2and 3 will not go but 5 will 125 = 5 x 25

Repeat this process with the 25

25 = 5 x 5

so we have 125 = 5x5x5 and therefore sqrt 125 = 5sqrt5

Not easy to see with this one but try 72

72 = 2 x 36 = 2x2x18= 2x2x2x9= 2x2x2x3x3

so sqrt72 = 2x3x root 2 = 6root2

You can improve on this method by using larger numbers once you get used to it.

72 = 2 x 36 = 2x6x6

so sqrt72 = 6 root2

Answer 4

Terrorism is nothing more than a form of guerrilla warfare that is vilified to turn the majority against the actions of the minority that is carrying out the terroristic actions. In other words, terrorism is just unconventional warfare. It's called terrorism to make the people committing the act look bad. What's the primary cause of warfare/what are people fighting over? Resources, or in other words, money, just like in any conflict. For example, when the Contras in Central America were fighting against the Sandinista government in Nicaragua in the '80's, they were called "Freedom Fighters" by the US and were given aid by the US government. The Contras did fight the Sandinistas (at times), but also carried out attacks against civilians, which included rape, torture, arson, and kidnapping. As a result, they were labeled "terrorists" by many other countries. Like the saying goes, "One man's terrorist is another man's freedom fighter".

Answer 5

There is an infinite number of roots. You probably mean the square root, but you must say so.

Answer 6

sq rt of 125 = sq rt of 25*5 = 5 sq rt of 5
