Quiz 1 - 4th

It refers to the number of times

a number is multiplied by itself.

• Real Number

• Exponent

• Law of Exponent

• Floating pOint Numbers

An equation in which the variable is in the exponent.

• Exponential Equation

• Floating Point Number

• Exponent

• Properties of Real Numbers

Which of the following is an example of Exponential Equation?

• $x^2\ =\ 6\ +\ y$

• $2_{3_{ }}+\ 4_2\ =\ y$

• $3^x\ =\ 27^{x-2\ }$

• $3\ +\ 4i$

 $Simplify:\ \ \frac{4x^{\frac{1}{2}}y^2z}{2x^2yz}$  

•  $\frac{2y}{x_{ }^{\frac{3}{2}}}$  

•  $\frac{4x^{\frac{1}{2}}y^2z}{2x^2yz}$  

•  $2x^{\frac{3}{2}}y$  

•  $2xyz$  

Solve for x: $4^{2x-1}\ =\ 8_{ }^2$  

• x = 1

• x = 2

• x = 3

• x = 4

Rewrite in logarithmic form:

5³ = 125

• log ₅ 125 = 3

• log ₃ 125 = 5

• log ₁₂₅ 5 = 3

• log ₅ 3 = 125

Rewrite in exponential form:

log₆36 = 2

• 6²=36

• 36²=6

• 2⁶=36

• 6³⁶=2

Which of the following set of ordered pair is a function?

• { (3,2), (4,-1), (3,3)}

• {(-1,2), (-5,0) (4, 0) , (2, 2)}

• {(-1,12), (-5,10) (5, -3) , (2, 12), (4, 2)}

• { (3,-1), (2,-1), (3,3) ( 2, 0) (6, 6)}

Which of the following value of x will satisfy the given function. $f\left(x\right)\ =\ \left(\frac{2}{3}\right)^{x-1}\ =\ \frac{81}{16}$  

• -3

• 2

• 3

• -2

Which of the following is NOT a Property of an Exponential Function?
