Alright, so if you know or you know a website where i can find a paragraph 'bout who invented fractions and exponents. I will apreciate it!!!
Thank you.

FRACTIONS:
The earliest known use of fractions is ca. 2800 BC as Ancient Indus Valley units of measurement.[citation needed] The Egyptians used Egyptian fractions ca. 1000 BC. The Greeks used unit fractions and later continued fractions and followers of the Greek philosopher Pythagoras, ca. 530 BC, discovered that the square root of two cannot be expressed as a fraction. In 150 BC Jain mathematicians in India wrote the "Sthananga Sutra", which contains work on the theory of numbers, arithmetical operations, operations with fractions.
EXPONENTS:
The term power was used by Euclid for the square of a line. Nicolas Chuquet used a form of exponential notation in the 15th century, which was later used by Henricus Grammateus and Michael Stifel. Samuel Jeake introduced the term indices in 1696.[19] In the 16th century Robert Recorde used the terms square, cube, zenzizenzic (fourth power), surfolide (fifth), zenzicube (sixth), second surfolide (seventh) and Zenzizenzizenzic (eighth). Biquadrate has been used to refer to the fourth power as well.
Who Invented Exponents
Pythagoras made things very easy, but he was wrong He believed that everything could be measured through integers and their ratio (fractions) You are right: people invented numbers and they have continued to invent new kind of numbers to answer to more and more difficult answers sqrt 2 works great build a square with side 1 unit draw the diagonal of the square: its length is sqrt 2 pi is a bit more difficult, but is easy to understand: circumference contains pi diameters the imaginary unit i is harder to understand i = √-1 XVIth century mathematicians used i normally, but they did not understand negative numbers, because numbers were measures of segments, area etc also powers greater than 3 were difficult to get for a similar reason I hope this is useful

People invented numbers to count with, and then arithmetic. As long as you stick with counting numbers and confine your arithmetic to adding and multiplying, everything "works out". But then somebody had 15 fish which he had agreed to divide up among a total of 4 people, and that doesn't "work out," so he or she invented fractions. Then people invented exponents as short-hand for repeated multiplications, but only some of the counting numbers are the results of repeated multiplications, so then people invented "radicals" such as the square root of 2. I think you get where I'm going with this...
