Since $y = x - 5$ in the second equation, we may substitute this fact into the first equation and then solve for $x$.
Doing so we get :
$x + \left(x - 5\right) = 23$

Question:
$x^{x^{2}-3}+(x-3)^{x^{2}}$, for $x>3$
Solution:
Let $y=x^{x^{2}-3}+(x-3)^{x^{2}}$
Also, let $u=x^{x^{2}-3}$ and $v=(x-3)^{x^{2}}$
$\therefore y=u+v$
Differentiating both sides with respect to x, we obtain
$\frac{d y}{d x}=\frac{d u}{d x}+\frac{d v}{d x}$ ...(1)
$u=x^{x^{2}-3}$

Order of Operation
While solving questions involving mathematical operations involving addition, subtraction, multiplication and division we follow a particular order while performing a calculation. To perform calculations we follow BODMAS.
BODMAS stands for
B = Bracket
O = of
D = Division

## Statement
For $k$ a positive integer, denote by $f^{(k)}$ the function obtained by differentiating $f$ a total of $k$ times. The operation $f \mapsto f^{(k)}$ is a linear operator. We give two equivalent ways of stating this below.

You are given two coins $A$ and $B$ that look identical. The probability that coin $A$ turns up heads is $\frac{1}{4}$, while the probability that coin $B$ turns up heads is $\frac{3}{4}.$ You choose one of the coins at random and toss it twice. If both the outcomes are heads, what is the probability that yo... |
