Answer: Question 1) No, because according to the law of exponents
x³.x³.x³ = x³⁺³⁺³ = x⁹
and x⁽³*³*³⁾ = x²⁷
Question 2) √x
Question 3) 4x
Question 4) ∛x²
Question 5) B = D
Step-by-step explanation:
Question 1) Is the expression x^3*x^3*x^3 equivalent to x^(3*3*3)? Why or why not? Explain your reasoning.
No, because according to the law of exponents
x³.x³.x³ = x³⁺³⁺³ = x⁹
and x⁽³*³*³⁾ = x²⁷
Question 2) Rewrite in simplest radical form 1/x^((-3)/6). Show each step of your process.
simplifying the denominator expoent: 1/x^((-3)/6) = 1/x^(-1/2)
apply the expoent to the hole fraction: 1/x^(-1/2) = (1/x)^(-1/2)
changing the signal on the expoent: (1/x)^(-1/2) = (x)^(1/2)
changing the expoent into root: (x)^(1/2) = √x
1/x^((-3)/6) = 1/x^(-1/2) = (1/x)^(-1/2) = (x)^(1/2) = √x
Question 3) Rewrite in simplest rational exponent form √x • 4√x. Show each step of your process.
√x • 4√x = 4√x • √x = 4√x² = 4x
Question 4) Rewrite in simplest radical formx^(5/6)/x^(1/6). Show each step of your process.
x^⁽⁵/⁶⁾/x^⁽¹/₆⁾ = x^⁽⁵/⁶⁾ • 1/x^⁽¹/₆⁾ = x^⁽⁵/⁶⁾ • x^⁽⁻¹/₆⁾ = x^⁽⁵/⁶ ⁻ ¹/⁶) = x^⁽⁴/⁶⁾ = x^⁽²/₃⁾ = ∛x²
Question 5) Which of the following expressions are equivalent? Justify your reasoning.
A. ⁴√x³ B. 1/x⁻¹ C. ¹⁰√x⁵•x⁴•x² D. x¹/³•x¹/³•x¹/³
A. ⁴√x³ = x³/⁴
B. 1/x⁻¹ = (1/x)⁻¹ = x
C. ¹⁰√x⁵•x⁴•x² = ¹⁰√x¹¹ = x¹¹/¹⁰
D. x¹/³•x¹/³•x¹/³ = x⁽¹/³⁺¹/³⁺¹/³⁾ = x³/³ = x
So, B = D
