Question

Lg 700000 - lg 7 Решите пожалуйста

Answer 1

Lg 700000 - lg 7 
log10(700000)-log10(7)
log10(700000/7)
log10(100000)=5

Answer 2

To solve the expression "lg 700000 - lg 7," let's first clarify that "lg" usually refers to the base-10 logarithm, which is commonly denoted as "log" in mathematics. So the expression can be rewritten as:

log(700000) - log(7)

To evaluate this expression, we use the logarithmic property:

log(a) - log(b) = log(a / b)

Applying this property to the given expression:

log(700000) - log(7) = log(700000 / 7)

Now, calculate the division:

log(100000) = log(100000) = 5

So the solution is 5.
