Question

Using the numbers 5, 8, and 24, create a problem using no more than four operations (addition, subtraction, multiplication, division, square, square root, cube, cube root) where the solution will be an irrational number. Explain why the result of your operations is an irrational number.

Answer 1

I dont understand how you do this?

Answer 2

Irrational numbers have to use either the square root or cube root, because all the "easy" operations like add, subtract, multiply, and divide leave you with either whole numbers or fractions.. both are rational.

Answer 3

Kind of a weird question...

Answer 4

Ya i figured tht part out i tried almost everyhting i could think of with division multiplacation and stuff

Answer 5

yes a very weird question indeed

Answer 6

but like would this make an irrational (5- (24/8))

Answer 7

maybe \[\sqrt{8+5+24}\] ?

Let's check it...

Answer 8

\[\sqrt{8+5+24} = \sqrt{37}\]

Answer 9

the square root of 37 is like inbetween 6 and 7 so id say its irrational isnt it?

Answer 10

that's irrational... yeah, you're correct about why too.

Answer 11

YES! whoot whoot

Answer 12

It doesn't say you have to use all the operations... just no more than 4... so I'd use that example with your reasoning.

Good work :)

Answer 13
