Question

help please

Answer 1

1.

Answer 2

145*? I don't get it

Answer 3

\[\frac{ 100 }{ 100 }\] is a whole, so as a number it is 1

Answer 4

the numerator is always the number and "percent" means /100

Answer 5

so 1.45?

Answer 6

YES

Answer 7

sorry my computer keeps refreshing the page but can you help me with number 2?

Answer 8

Yes it works the same way, percentage is always a ratio
\[\% = \frac{ }{ 100 }, \]\[x \% = \frac{ (x ) }{ 100 }.\]

Answer 9

2 43/100?

Answer 10

YES !!

Answer 11

43/100 = 0.43/1

Answer 12

thank you. can you help me with some more?

Answer 13

sure

Answer 14

do you know what a square root is?

Answer 15

yes

Answer 16

\[\sqrt{16} = 4\]

Answer 17

so we're looking for a number that, when squared, will give the one under the root

Answer 18

one that when multiplied with itself, will be the one under the root

Answer 19

so for number 4 it will be C?

Answer 20

well I think I confused you

4*4 is a square (of 4) and is 16 , but that's not a good estimation for 10

the post above was just an example for how a square root works,
could have also used
\[\sqrt{9} = 3\]

Answer 21

ohhh so its D right

Answer 22

For the problem 4) you're looking for a square (REQUIREMENT so it works with roots) that is close to 10

Answer 23

yes

Answer 24

D)
- is a square (number multiplied with itself)
- the result is 9, which is close to 10

Answer 25

thank you. can you help with number 5?

Answer 26

There you need to be familiar with exponent rules

Answer 27

What can this be written using no exponents?
\[6^3\]

Answer 28

uh I'm not sure about that..

Answer 29

sorry my computer keeps failing so im on my phone

Answer 30

it can be written like this:
\[6 \times 6 \times 6\]

Answer 31

so would it be A?

Answer 32

\[6^{-3} = \frac{ 1 }{ 6 \times 6 \times 6 }\]
If the exponent is negative, it means take reciprocal after applying the typical exponent operation

Answer 33

so it's either B or C?

Answer 34

I want to say b but I'm not sure

Answer 35

the second part is 5^-4

step by step: what will this be?
\[5^4\]

Answer 36

C!!
