Exponential Equations and Their Solutions

The video tutorial explains how to solve a challenging exponential equation. It begins with setting up the problem and using cross multiplication to simplify the equation. The tutorial reviews exponent rules and adjusts the equation accordingly. It then combines fractions and simplifies further before using substitution to factor the equation. After solving the factored equation, the solution is verified through substitution, ensuring the answer is correct.

What is the first step recommended to solve the given exponential equation?

• Add the fractions

• Multiply both sides by 10

• Cross-multiply the fractions

• Subtract the fractions

How do you simplify 4 raised to the x using exponent rules?

• 4 raised to the x is equal to 4 raised to the 2x

• 4 raised to the x is equal to 4 raised to the x plus 1

• 4 raised to the x is equal to 4 raised to the 2x divided by 4 raised to the 1x

• 4 raised to the x is equal to 4 raised to the 2x divided by 4 raised to the x

What is the result of combining the fractions with the same denominator?

• 4 raised to the 2x divided by 4 raised to the x

• 4 raised to the 2x times 1 over 4 raised to the x

• 4 raised to the 2x minus 1 over 4 raised to the x

• 4 raised to the 2x plus 1 over 4 raised to the x

What substitution is made to simplify the exponential equation?

• a is equal to 4 raised to the 2x

• a is equal to 4 raised to the negative x

• a is equal to 4 raised to the x

• a is equal to 4 raised to the x squared
