When answering "你好吗？" (Nǐ hǎo ma) why do you answer with "我很好" (Wǒ hěn hǎo) and not "我是好" (Wǒ shì hǎo)?

In the Chinese language, 是 (shì) is generally not used for adjectives. 是 (shi) is used for connecting two nouns, such as 我是美国人 (Wǒ shì měiguó rén). The two nouns here is 我 (Wǒ), I, and 美国人 (měiguó rén), American person. When answering 你好吗？ (Nǐ hǎo ma), 好 (hǎo) is an adjective and describing the subject of the sentence. When following a noun with an adjective, we can omit the use of 是 (shì).

Which of these are current or non-current? Accounts Payable, Cash, Property, Plant, and Equipment, Note Payable, Inventory

Accounts Payable is a current liability because they occur within the year or accounting period. Cash is also a current asset because of this reason. Property, Plant, and Equipment is a non-current asset because these are not easily liquidated. They usually take more than one year to sell. Note Payables would also be a non-current liability as they are due after a year. Inventory is a current asset because businesses intend to sell inventory and convert to cash within the year or period.

How would you simplify (x^4 / x^3)^3?

First, you would have to distribute the exponent 3 outside of the parenthesis to the exponents of x^4 and x^3. When distributing the exponent, you have to multiply the 3 by 4 for the numerator and 3 by 3 for the denominator. After doing this, you should get (x^12 / x^9). When you divide variables with exponents, you can simply subtract the top exponent by the bottom exponent (12-9). As a result, you would end with x^3 as the final answer.
