Q. Find the positive solution of the equation.4x65+6=4102Answer:
Isolate variable term: Isolate the term with the variable.Subtract 6 from both sides of the equation to isolate the term with the variable x.4x(5/6)+6−6=4102−64x(5/6)=4096
Subtract to isolate x: Divide both sides by 4 to solve for x65.44x65=44096x65=1024
Divide to solve x65: Recognize that 1024 is a power of 2. 1024 is 2 raised to the power of 10 because 210=1024. x65=210
Recognize power of 2: Write the equation in terms of a common base.Since we have x65=210, we can express x as 2 raised to some power.Let's find the power that 2 must be raised to in order to get x by equating the exponents.(65)×(the power of 2 that gives x)=10
Write in common base: Solve for the power of 2 that gives x.Multiply both sides of the equation by 56 to solve for the power of 2.56×65×(the power of 2 that gives x)=56×10(the power of 2 that gives x)=12
Solve for power of 2: Write x as 2 raised to the power of 12.Since the power of 2 that gives x is 12, we can write x as 212.x=212
Write x as 212: Calculate the value of 212. 212=2×2×2×2×2×2×2×2×2×2×2×2 212=4096
