Question

Write 2,5,8,9 in a combination of irrational and rational numbers.
It should be written as an expression like
7 = root147/root3

Answer 1

Answer:

2=

$\sqrt{ \frac{64}{16} }$

5=

$\sqrt{ \frac{225}{9} }$

8=

$\sqrt{ \frac{576}{9} }$

9=

$\sqrt{ \frac{729}{9} }$

explaination:

for example let's take 2

2*4 =8

therefore, 8/4 =2

so 8^2/4^2 = 2^2

which is 64/16 =4

to get 2

root64/root16 = 2

hope this helps
