Ok so i have the weekend to do my homework,so i can correct it if it's wrong, but this is a true or false question.
I write square root because i don't know the alt keys to make the actual symbol.
The square root of 16 - square root of 9 = square root of 7.I put false because the square root of 16 is 4, the square root of 9 is 3,and the square root of 7 is 2.645
so, 4-3=1, not 2.645, that's my logic,is it correct?thanks because i have alot of questions like this.
Also, when the square root symbol is around 100 divided by 25(by around i mean the 100 and 25 are inside the square root symbol), which looks like 100 and under it is 25 seperated by a horizontal line,which i took to be division.Anyway back to my question,if the square root symbol is around the 100/25, do i do 100 divided by 25 first,so 4,then do the square root of 4 equalling 2?Please help, there is no instructions on how to do this in my excersise book.
