Question

if log 4 is equals to zero point 6020 then find the value of log 80​

Answer 1

Answer:

1.9030

Step-by-step explanation:

we know that

log(A×B)=logA+ logB

then

we have

log80

then we write that

log(20×4)=log20+log4

=log(10×2)+log4

=log10+log2+log4

=1+0.3010+0.6020

=1.9030

Answer 2

The value of log 80 is 1.903.

Step-by-step explanation:

Since we have given that

log 4 = 0.6020

so, log 4 = $\log 2^2=2\log 2$

So, it becomes,

$0.6020=2\log 2\\\\\dfrac{0.6020}{2}=\log 2\\\\\log 2=0.3010$

Now, it becomes,

$\log 80=\log (2\times 4\times 10)\\\\\log 80=\log 2+\log 4+\log 10\\\\\log 80=0.3010+0.6020+1\\\\\log 80=1.903$

Hence, the value of log 80 is 1.903.
