k
15,013
51
[]
volunteer
okay so I see that you solved it
15,013
52
[]
volunteer
did you wanna check if its right?
15,013
53
[]
student
No
15,013
54
[]
student
I want a problem just like that but with different numbers
15,013
55
[]
student
So I can solve the one you create
15,013
56
[]
volunteer
Oh for practice
15,013
57
[]
student
yes
15,013
58
[]
volunteer
Yea um the picture quality on the image you sent me isn't great so I can't actually read the original question
15,013
59
[]
volunteer
i can only read the answer because it's in bigger numbers
15,013
60
[]
student
ill write out what it says
15,013
61
[]
volunteer
k
15,013
62
[]
student
3^-1+2^2-?5/3)^-2
15,013
63
[]
volunteer
okay let me think
15,013
64
[]
volunteer
(4^-1)+(3^2)-(4/3)^-2
15,013
65
[]
student
can u write it on the whiteboard
15,013
66
[]
volunteer
sure
15,013
67
[]
student
thanks
15,013
68
[]
volunteer
No problem!
15,013
69
[]
student
ok so its
15,013
70
[]
student
-4?
15,013
71
[]
volunteer
Not quite. This one is a bit tricky but the answer 12/16
15,013
72
[]
student
no im asking about the first part
15,013
73
[]
student
like how do u solve this
15,013
74
[]
volunteer
Okay let me walk you through it
15,013
75
[]
volunteer
so first we need to simplify the terms
15,013
76
[]
volunteer
4^-1 is the same thing as 1/4
15,013
77
[]
student
ohh right
15,013
78
[]
volunteer
3^2 is the same thing as 9
15,013
79
[]
student
mhm
15,013
80
[]
student
and then its -8/3?
15,013
81
[]
volunteer
and (4/3)^-2 is the same thing as (3/4)^2 because we flip the fraction so we flip the sign. And (3/4)^2 is the same thing as just 9/16.
15,013
82
[]
volunteer
and so now we have 1/4 + 9 -9/16
15,013
83
[]
student
wait
15,013
84
[]
student
can u show this on the whiteboard please
15,013
85
[]
volunteer
yea
15,013
86
[]
student
its gone
15,013
87
[]
volunteer
yea i wanted to make space for the new simplified equation
15,013
88
[]
student
wait
15,013
89
[]
student
i have written down 1/4+9(-4/3)^2
15,013
90
[]
volunteer
oh its supposed to be what I've written on the board
15,013
91
[]
volunteer
because we had simplified (4/3)^2
15,013
92
[]
volunteer
sorry we had simplified (4/3)^-2
15,013
93
[]
student
oh you flip it
15,013
94
[]
student
k i see
15,013
95
[]
volunteer
Yup!
15,013
96
[]
student
ok
15,013
97
[]
student
now what
15,013
98
[]
student
tims 1/4 by 4?
15,013
99
[]
volunteer
yea basically to make it so that its 4/16 because thats the same thing has 1/4
15,013
100
[]
student
kk
15,013
101
[]
volunteer
so now
15,013
102
[]
volunteer
we need to make 9 a fraction
15,013
103
[]
student
so its
15,013
104
[]
volunteer
with the denominator as 16
15,013
105
[]
student
4/16+9-9/16
15,013
106
[]
volunteer
Yes!
15,013
107
[]
student
so i do 4/16
15,013
108
[]
volunteer
not yet
15,013
109
[]
student
kk
15,013
110
[]
volunteer
we need to turn 9 into a fractoin
15,013
111
[]
volunteer
with a denominator of 16
15,013
112
[]
student
oh right
15,013
113
[]
volunteer
so we now need to multiply 16 by 9
15,013
114
[]
volunteer
which would 144
15,013
115
[]
student
144/16
15,013
116
[]
volunteer
Yes!
15,013
117
[]
volunteer
now plug that in back into the equation
15,013
118
[]
student
139/16
15,013
119
[]
volunteer
Yes! That is your answer!
15,013
120
[]
