Answer:
(14n - 42)*pi
Step-by-step explanation:
Circumference is 2 * pi * r. Since r in this case is 7n - 21, you can multiply r by 2 and pi, giving you (14n - 42)*pi
The expression as a power is x¹⁰.
Given, the expression is xx⁴x⁴x
In exponents we have the power rule while multiplying.
the rule is that when bases are same, powers are added.
Exponent multiplication is the process of multiplying two terms with exponents. Depending on the base and the power, specific rules apply when multiplying exponents.
⇒ xx⁴x⁴x
base is same, power should be added.
⇒ x¹⁺⁴⁺⁴⁺¹
= x¹⁰
Hence the expression as a power is x¹⁰.

<u>Answer-</u>
The equation is 
and Julianne will begin making a profit after 168 days.
<u>Solution-</u>
Julianne's start-up cost = $52,000,
Each day, she spends = $650,
and she earns = $960 per day,
If 'd' is the number of days to overcome the start-up and daily operation cost, then
total operation cost of d days = $650d and
total student lesson fees earned in d days = $960d
∴ The equation to represent the situation is,
∴ Julianne will begin making a profit,
