Am nevoie mare dace se poate sa le rezolvați cu tot cu modul în care ați lucrat ​

Answer 1

Răspuns:

5. a) $\sqrt{\frac{16}{25}$=raradical4^2/radical25=radical4^2/radical5^2=4/radical5^2=4/5

radical=r

b)$\sqrt{\frac{81}{64} }$=$\sqrt{\frac{21}{16} }$=r21/4

c)$\sqrt{} \frac{9}{49}$=r3^2/r49=r3^2/r7^2=3/r7^2=3/7

g)$\sqrt{} \frac{196}{289}$=r14^2/r17^2=14/r17^2=14/17

h)$\sqrt{} \frac{625}{324}$=r25^2/r18^2=25/r18^2=25/18

i)$\sqrt{} \frac{169}{256}$=r13^2/r16^2=13/r16^2=13/16

m)$\sqrt{} \frac{576}{729}$=64/81=8/9

n)$\sqrt{} \frac{784}{1225}$=$\sqrt{} \frac{16}{25}$=4/5

6. a)r2.7/9=$\sqrt{} \frac{25}{9}$=5/3

b)r5.19/25=$\sqrt{} \frac{144}{25}$=12/5

f)r4.25/36=$\sqrt{} \frac{167}{36}$=r167/6

g)r4.33/64=$\sqrt{} \frac{289}{64}$=17/8
