Question

ajutor pls, repede dau coroana​

Answer 1

8. a) $6\sqrt{3}$ = $\sqrt{108}$

b) $5\sqrt{5}$ = $\sqrt{125}$

c) $9\sqrt{2}$ = $\sqrt{162}$

d) $4\sqrt{7}$ = $\sqrt{112}$

e) $5\sqrt{6}$ = $\sqrt{150}$

f) $7\sqrt{3}$ = $\sqrt{147}$

g) $6\sqrt{5}$ = $\sqrt{180}$

h) $5\sqrt{7}$ = $\sqrt{175}$

9. a) $-4\sqrt{3}$ = $-\sqrt{48}$

b) $-5\sqrt{2}$ = $-\sqrt{50}$

c) $-2\sqrt{7}$ = $-\sqrt{28}$

d) $-3\sqrt{5}$ = $-\sqrt{45}$

e) $-7\sqrt{5}$ = $-\sqrt{245}$

f) $-9\sqrt{6}$ = $-\sqrt{486}$

g) $-5\sqrt{8}$ = $-\sqrt{200}$

h) $-6\sqrt{7}$ = $-\sqrt{252}$

10. a) $\sqrt{245}$ = $7\sqrt{5}$

b) $\sqrt{300}$ = $10\sqrt{3}$

c) $\sqrt{320}$ = $8\sqrt{5}$

d) $\sqrt{252}$ = $6\sqrt{7}$

11. a) $\sqrt{720}$ = $12\sqrt{5}$

b) $\sqrt{588}$ = $14\sqrt{3}$

c) $\sqrt{675}$ = $15\sqrt{3}$

d) $\sqrt{648}$ = $18\sqrt{2}$

12. a) $\sqrt{20}$ = $a\sqrt{5}$  => a = 2

b) $\sqrt{63}$ = $a\sqrt{7}$  => a = 3

c) $\sqrt{45}$ = $a\sqrt{5}$  => a = 3

d) $\sqrt{294}$ = $a\sqrt{6\\}$  => a = 7

e) $\sqrt{243}$ = $a\sqrt{3}$  => a = 9

f) $\sqrt{338}$ = $a\sqrt{2}$  => a = 13

13. a) $4\sqrt{3}$ = $\sqrt{n}$  => $\sqrt{n}$ = $\sqrt{48}$

b) $5\sqrt{6}$ = $\sqrt{n}$  => $\sqrt{n}$ = $\sqrt{150}$

c) $7\sqrt{2}$ = $\sqrt{n}$  => $\sqrt{n}$ = $\sqrt{98}$

d) $6\sqrt{10}$ = $\sqrt{n}$  => $\sqrt{n}$ = $\sqrt{360}$

e) $3\sqrt{15}$ = $\sqrt{n}$  => $\sqrt{n}$ = $\sqrt{135}$

f) $2\sqrt{17}$ = $\sqrt{n}$  => $\sqrt{n}$ = $\sqrt{68}$
