Hi friends,

another of those.."simplify with the aid of logarithmic laws"

They also want to see all steps...

$${x={{13,4^5* \sqrt265} \over (12,8)(54,6)}}$$

Is that really 13.55   in the numerator??    Using a calculator ,    I get x = 10063.39

Hi ElectricPavlov,

Well   x does not equal 10            for       (13.4)5 * sqrt(265)  / (12.8 * 54.6)

it equals 10063.39

Juriemagic,

These questions are not making sense.

I am wondering if you are interpreting them incorrectly.

If possible, could you please post a picture of the actual question?   Like maybe a screenshot. Or a photo.

Also, it might help to know what country you are in as symbols can mean different things in different countries.

South Africa has got the best beaches in the world do I am told. No laughing matter at all.

Anyway, can you provide us with a pic of your question?
