No estoy segura e -2 ao quadrado esa es toda la pregunta
Answer:
I have solved the question in the picture in two different ways : simplification and factorisation I hope you find it useful bye:)
That easiliy false. You can prove this by observing that all integers are, in particular, rational numbers. So, for instance, you can think of 4 as
, so 
And obviously, you have 
It is true that the square of every rational number between 0 and 1 is smaller than the number itself.
But since not all rational numbers are between 0 and 1, the general claim is false.
The square root of 141 =

This is because the two factors are 3 and 47, which both aren't perfect squares. You cannot take anything out.
If you want it simplified (like with a calculator) it would be:
♥ To start you are going to divide

♥ Solve:

♥ Now multiply this by 100.

♥ Solve:
35

Now you have your final answer: 35%
