Question

y = log x
If y = 10, then what is x?

Answer 1

what do you know about logs?

Answer 2

The logarithm of a number is the exponent by which another fixed value, the base, must be raised to produce that number. For example, the logarithm of 1000 to base 10 is 3, because 1000 is 10 to the power 3: 1000 = 10 × 10 × 10 = 103. More generally, if x = by, then y is the logarithm of x to base b, and is written y = logb(x), so log10(1000) = 3.

Answer 3

nice copy and paste of a definition, dude
what do you understand about logs?

Answer 4

nothing

Answer 5

lol

Answer 6

well we can try to understand your definition as a start

Answer 7

10=10^x

Answer 8

but is this the right way

Answer 9

When you see a logarithm like y=log x ask yourself the question, "to what power must I raise 10 (the base) to get x?" If y is 10 then x is 10^10.

Answer 10

\[2\times2\times2=(2)^3=8\]
In this case, your logarithm is 3
and we can write it like this
\[\log_{2} (8)=3\]

Answer 11

r u sure

Answer 12

i have to solve for x

Answer 13

the number we are multiplying is called base, so we can say that:
the logarithm of base 2 is 3

Answer 14

I am providing you the fundamental concept to logarithms

Answer 15

nvm i will google it

Answer 16

you will get the same concept as what I am teaching you now

Answer 18

ok so i get it now so its
y = log x
10 = log x
10 = 10^x
x = 1

Answer 19

@RAWFECTION

y = log x
10 = log x
10 = 10^x
x = 1

this is not done correctly. x is not equal to 1... log1 equals zero, not 10.

Answer 20

Correct solution is: \[ \log_{10} x = 10\] so
\[\large 10^{10} = x\]
^that is x.


This comes from this rule:
\[\large \log_{a} x = b\] then \[\large a^b = x\]
