Question

how do i express the number 29.73213749 in a radical form?

Answer 1

why would you want to?

Answer 2

... did you get that on your calculator and need to match it up to an option by chance?

Answer 3

\[a = x^{1/n}\]
\[a^n = x\]

Answer 4

I got that number on my calculator after finding the square root of 884 and i was ask to put it in radical form if its not an integer

Answer 5

you might just want to work the radical on paper then ...

Answer 6

but i dont know how to do radicals

Answer 7

its a sqrt ...

just start halving it until you get to an odd value

Answer 8

884

2 * 442
2 * 221
etc ...

what are any factors of 221?

Answer 9

13 and 17

Answer 10

and those are prime

so it looks like 884 = 2*2*17*13

sqrt(884) = sqrt(2*2*17*13)

anything that is doubled can be pulled out

sqrt(2*2*17*13) = 2 sqrt(17*13)

so id say its simply 2 sqrt(221)
