4c2 + 7c
8c2 + 5c
8c2 + 7c

Answer 1

\[\sqrt{16c4} - \sqrt{c2} + 3 \sqrt{c2} + \sqrt{9c2}\]

Answer 2

nice latex !

Answer 3

simplify each term first

Answer 4

take first term :

\(\sqrt{16c^4}\)

Answer 5

ok

Answer 6

tell me this,

when u square, which number gives you \(16\) ?

Answer 7

4 squred is 16

Answer 8

yes !

so when u take square root of 16, u wil get 4 back

Answer 9

\(\sqrt{16} = \sqrt{4^2} \)
= \( 4\)

Answer 10

the "square" and "square root" cancel out

Answer 11

ok

Answer 12

lets go back tofirst term :

\(\sqrt{16c^4}\)

\(\sqrt{4^2(c^2)^2}\)

\(4c^2\)

Answer 13

lets do the whole expression :-

Answer 14

ok

Answer 15

\(\sqrt{16c4} - \sqrt{c2} + 3 \sqrt{c2} + \sqrt{9c2} \)

\( 4c^2 - c + 3 c+ 3c \)

simplify

Answer 16

The answer is 4c2 + 5c

Answer 17

Whic is the first answer.
