Question

(31g2 + lg0,25) : (lg14 - log7) Help

Answer 1

=lg(8*0.25)/lg2=lg2/lg2=1

Answer 2

Solving the Expression (31g2 + lg0.25) : (lg14 - log7)

To solve the given expression (31g2 + lg0.25) : (lg14 - log7), we can start by evaluating the logarithmic terms and then proceed with the arithmetic operations.

First, let's evaluate the logarithmic terms: - lg0.25 = -2 [[1]] - lg14 ≈ 1.14612803567824 [[2]] - log7 ≈ 0.845098040014257 [[3]]

Now, we can substitute these values back into the original expression: (31g2 - 2) : (1.14612803567824 - 0.845098040014257)

Next, we can perform the subtraction inside the parentheses: (31g2 - 2) : 0.301029995663983

Finally, we can perform the division: 31g2 - 2 / 0.301029995663983

This simplifies to: 31g2 - 6.63987741612022

So, the result of the expression (31g2 + lg0.25) : (lg14 - log7) is 31g2 - 6.63987741612022.
