Question

C={7^x+y=343, solution set of (x ,y)}

Answer 1

Step-by-step explanation:

Given:-

C={7^x+y=343}

To find:-

Find the solution set for C={7^x+y=343}

Solution:-

Given set C={7^x+y=343}

=> 7^(x+y)=343

=> 7^(x+y)=7×7×7

=> 7^(x+y)=7^3

On Comparing both sides then

=> x + y = 3

If x and y natural numbers then the solutions are (1,2),(2,1)

Solution set ={(1,2),(2,1)}

If x and y are whole numbers then the solution set = {(0,3),(1,2),(2,1),(3,0)}

Answer:-

• If x and y natural numbers then theSolution set ={(1,2),(2,1)}
• If x and y are whole numbers then the solution set = {(0,3),(1,2),(2,1),(3,0)}
