Answer:
Joni's mistake was to multiply the exponents instead of adding the exponents.
Step-by-step explanation:
we know that
When multiplying two powers that have the same base, you can add the exponents
so
![d^{3} *d^{11} =d^{3+11}=d^{14}](https://tex.z-dn.net/?f=d%5E%7B3%7D%20%2Ad%5E%7B11%7D%20%3Dd%5E%7B3%2B11%7D%3Dd%5E%7B14%7D)
Joni's mistake was to multiply the exponents instead of adding the exponents.
Answer:
To solve this you must first know how Log works.
When we say log1000 of base 10
Or
log1000=3
What we actually say is for the power 3(value on RHS) of 10(the base of log) we get 1000(the value on which log is performed).
So log2x=−5 (i am assuming base 10 since it is simple algebra) means that
2x=10−5
x=10−5/2
Do this simple calculation and you have it. If anything is unclear/incorrect feel free to comment.
The question is not written properly, so I will give the answer(s) I think would be suitable.
If you were trying to solve this
log2x=−5
⟹x=2−5
⟹x=132
But if you were trying to solve this
log2x=−5
⟹log102x=−5
⟹2x=10−5
⟹x=12×105=1200000

10>X>0 this is x being greater than 0 and less than 10
Answer:
15. y = 6x
16. x = 11
Step-by-step explanation:
15. A direct variation equation is of the form ...
y = kx
Solving for k, we find ...
k = y/x = 42/7 = 6
The equation is y = 6x.
__
16. Filling in the given values, we have ...
66 = 6x
11 = x . . . . . . . divide by 6
