Mathematiciansin the house, Come in and solve this maths.

Cassandraloius:
Mathematics is not for the weak.

FalseProphet1:
As a prophet, this isn't my calling. I'm supposed to be seeing visions, not cracking my head in this Tinubu's economy to solve mathematics.

This I have seen.

Your answer is 0.

Please share the steps for displaying this the way it is. I imagine you use latex.

Kay25:
All dis maths never made person rich like dangote noni

Omoawoke:
From the way I asked the question, I’m sure you realize I know what I’m talking about. I know the application of logarithms and exponential. It’s just the way education is being taught in Nigeria. People solve different mathematical equations without knowing the applications

The answer is approximately 1-1/e = 0.632. I will upload the workings when I get to my laptop.

Edit:
See the attached image for the evaluation

But riches man Elon musk uses it to build rockets, smart cars and even satellites

Yeah, I used latex with the Verbtex app, a latex editor for Android (https://play.google.com/store/apps/details?id=verbosus.verbtex). This is the latex source file:

\documentclass{article}
% Allow the usage of UTF-8 characters
\usepackage[utf8]{inputenc}
% Allow the usage of graphics (.png, .jpg)
\usepackage{graphicx}

\newcommand{\num}{8\times 10^{67}}

% Start the document
\begin{document}

% Create a new 1st level heading
\section*{}

The main idea is to observe that $\num$ is a large number and then use limit. It is known that $\lim\limits_{x\to \infty} \left(1-\frac{1}{x}\right)^x = \frac{1}{e}$. Hence, the expression $1 - \left(1-\frac{1}{\num}\right)^{\num} \approx 1-\frac{1}{e} \approx 0.632$.

Note that commonly available calculators cannot accurately evaluate the given expression. Due to their limited numerical precision, they evaluate $\frac{1}{\num}$ as zero, thus incorrectly giving the final answer as 0.

To correctly evaluate the expression numerically, one may use MATLAB, Octave, or any other computational software that supports variable-precision arithmetic. The one-line code in MATLAB or Octave is: \\
\\
vpa(1 - (1-1/sym(8e67))\^{}sym(8e67), 64)
\\

The second argument (\textbf{64}) passed to the \textbf{vpa} function is the number of significant digits in the final answer. Setting it too low will result in inaccurate evaluation.

I don't like mathematics at all and i so much envy those that knows mathematics. Na like say dem dey do magic with numbers.

Where in the world is application of logarithms taught
You guys should calm down with this oversabi
It's even obvious you don't understand what logarithms are to be asking for its application
It's just like asking for the application of Ztable or sin table
