Kiran and Mai are trying to figure out if this equation is an identity, what do you think
ValentinkaMS [17]

Expanding the left side of the equation, it is found that since <u>both sides are equal</u>, yes, it is an identity.

An equality represents an identity if <u>both sides are equal</u>.

In this problem:

(a - b)^4 = a^4 - 4a^3b + 6a^2b^2 - 4ab^3 + b^4

Expanding the left side:

(a - b)^2(a - b)^2 = a^4 - 4a^3b + 6a^2b^2 + 4ab^3 + b^4

(a^2 - 2ab + b^2)(a^2 - 2ab + b^2) = a^4 - 4a^3b + 6a^2b^2 - 4ab^3 + b^4

a^4 - 4a^3b + + 6a^2b^2 - 4ab^3 + b^4 = a^4 - 4a^3b + 6a^2b^2 - 4ab^3 + b^4

Since <u>both sides are equal</u>, yes, it is an identity.

Please find the derivative of <img src="https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7Be%5E%7B%5Cfrac%7B3%7D%7Bx%7D%7D%7D%7

Hello! :)

\large\boxed{\frac{-e^{\frac{3}{x}}  (3 + 2x )}{x^{4}}}

Find the derivative using the quotient rule:

\frac{f(x)}{g(x)} = \frac{g(x) * f'(x) - f(x) * g'(x)}{(g(x))^{2}}

In this instance:

f(x) = e^{\frac{3}{x} }\\\\g(x) = x^{2}

Use the following properties to find the derivative of f(x) and g(x):

e^{u} = u' * e^{u}\\\\x^{n} = nx^{n-1}

Use the quotient rule:

\frac{x^{2} * (e^{\frac{3}{x}} * (-3x^{-2})) - e^{\frac{3}{x}} * 2x  }{(x^{2} )^{2}}

Simplify the numerator:

\frac{(e^{\frac{3}{x}} * (-3)) - e^{\frac{3}{x}} * 2x  }{(x^{2} )^{2}}

Factor out e^{\frac{3}{x}}

\frac{e^{\frac{3}{x}}  (-3 - 2x )}{x^{4}}

Factor out -1 from the numerator:

\frac{-e^{\frac{3}{x}}  (3 + 2x )}{x^{4}}

And we're done! Thanks for posting the question to my 1000th answer!
