Question

# The solution set of the system of equations, is

Hint:

### In this question, we have found the value of x and y. we have given two equations. Use the property of logarithmic and solve both equations to find relation between x and y.

## The correct answer is:

In this question, we use logarithmic property to solve the equation. Remember. Here solve both equation and find the relation between x and y and then put any variable value in one relation and find one variable.

Number of cyphers after decimal before a significant figure comes in is

In this question, we have to find the number of cyphers. We need to remember that the cypher number can be found from the logarithmic calculation but to find the actual value or to visualize it we need to remove the logarithm. Here, log_{10}5 = 0.6990 and log_{10}3 = 0.4770.
