The unit price rounded to the nearest cent would be .84
The answer will be Log₁₀[(20(x⁵)]-1. So the correct answer will be option E.
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
The solution to the given expression is as follows:-
E = 5Log₁₀x + Log₁₀(20) - Log₁₀10
{ By applying logarithmic properties:-
aLog₁₀b= Log₁₀b^a and Log₁₀a + Log₁₀ b = Log₁₀ ( a x b) and Log₁₀10 = 1 }
E = Log₁₀(x)⁵ + Log₁₀(20) - 1
E = Log₁₀[20(x)⁵]-1
Therefore answer will be Log₁₀[(20(x⁵)]-1. So the correct answer will be option E.

Answer:
c = 6
Step-by-step explanation:
have a nice day :)
Given expression is x² - 121
This is called Difference of Squared terms, we have a formula that is given as :-
a² - b² = (a - b) · (a + b)
Now using the above formula in the given expression, we get :-
x² - 121
x² - (11)²
here a = x and b = 11
x² - (11)² = (x - 11) · (x + 11)
but it says that student gave the answer as (x - 11) · (x - 11).
So, student's answer should be (x - 11) · (x + 11) instead of product of two (x - 11) terms.
Would it be 0.7 maybe right
