Answer 7

O i did it wrong

Answer 8

the screenshot helps!

can you show your simplifications?

Answer 9

how did u do it:

Answer 10

U had write it wrong lol

Answer 11

lel yea sorry

Answer 12

and hartann idk how

Answer 13

try to factor 8?

Answer 14

2.82842712474619

Answer 15

do u mean sqr?

Answer 16

i meant
\(8 = 2\times 2\times2\)

Answer 17

i think A is wrong

Answer 18

o

Answer 19

similarly, can you factor 75, 45 and 28?

Answer 20

isnt b wrong?

Answer 21

i got 81 for b:\

Answer 22

Be is right

Answer 23

B*

Answer 24

how?im so confused

Answer 25

Ask hartnn

Answer 26

he can explain if its right or wrong

Answer 27

let me do one for you,
try doing others similarly

\(\Large \sqrt{75} = \sqrt{3\times 5\times 5} = \sqrt 3 \times \sqrt{5\times 5} \\ \Large = \sqrt 3\times \sqrt{5^2} = \sqrt 3 \times 5 = 5\sqrt 3 \implies true\)

Answer 28

o ok

Answer 29

try to understand the steps,
and let me know if you don't get any of the steps

Answer 30

hows there 2 5's?

Answer 34

:D ^^^

Answer 35

thats why the first step is to factor

now try to factor 45 and 28

Answer 36

15*3=45
5*9=45

Answer 37

thx jay

Answer 38

by 3*5

Answer 39

so we have
\(\sqrt {45} = \sqrt{5} \times \sqrt 9\)

and whats the square root of 9 ?

Answer 40

3

Answer 41

yeah
so we have
\(\sqrt{45} = 3\sqrt 5 \implies true\)

Answer 42

how about factoring 28?

Answer 43

2*14=28
4*7=28

Answer 44

good
so we have
\(\sqrt{28} = \sqrt 4 \sqrt 7 \)

and whats the square root of 4 ?

Answer 45

2

Answer 46

\(\sqrt{28} = 2\sqrt 7\)


so
\(\sqrt{28}= 4\sqrt 7 \: \: is \: \: false.\)

Answer 47

o ok

Answer 48

can you try with \(\sqrt 8\) ?

hint 8 = 2*2*2

Answer 49

2*4=8 so its false??

Answer 50

\(\sqrt 8 = \sqrt{4 \times 2} = 2 \sqrt 2\)
so yea false

Answer 51

o ok
