Which expression is NOT a solution to the equation 2^t = √10?

• log base 2 of 10^2

• log base 2 of √10

• log base 4 of 10

• log base 10 of 4

What is the purpose of using the base switch formula?

• To simplify radical expressions

• To find the derivative of a function

• To convert logarithms to a common base

• To solve quadratic equations

How do you convert log base 4 of 10 to log base 10?

• Divide log of 10 by log of 4

• Subtract log of 4 from log of 10

• Multiply log of 10 by log of 4

• Add log of 10 and log of 4

What is the result of dividing log of 10 by log of 4?

• 0.301

• 1.660

• 0.602

• 2.000

What is the first step in solving the equation x = √(3x + 40)?

• Take the square root of both sides

• Square both sides

• Subtract x from both sides

• Add 40 to both sides

After squaring both sides of x = √(3x + 40), what is the resulting equation?

• x^2 = x + 40

• x^2 = 3x - 40

• x^2 = 40

• x^2 = 3x + 40

What are the potential solutions for the equation x^2 - 3x - 40 = 0?

• x = -5 and x = 8

• x = 5 and x = 8

• x = -5 and x = -8

• x = 5 and x = -8

Why is x = -5 rejected as a solution for the equation x = √(3x + 40)?

• It is less than -8

• It is greater than 8

• It is not a real number

• It does not satisfy the original equation

What is the correct solution set for the equation x = √(3x + 40)?

• {-5, 8}

• {5, -8}

• {8}

• {-5}
