Same here blockey, and I Can hardly remember my age and birthday, much less memorize any vocab definition.
I like science too I mean, math isnt hard, but I just dont like it, so I dont pay much attention to it. Im kinda like the "at the moment" kinda guu. Whatever i learn that day I ace it... But I forget it lile a month later Short term memory loss... Lol. Unless its important.. Like the formula for how to solve fir X on a triangle and stuff is long gone... lol
Short term memory loss goes well with me in just about any social science. Anything such as history or government is just memorize for test and forget immediately after. Never happens to me with math though I still remember math
Well this whole exam thing I'll be studying hard for. Future depends on it.... Lol. THIS is important. ha
When you square root an entire fraction, that is the same as square rooting the numerator and square rooting the denominator. In other words, if you have the square root of (1/4) then that's the square root of 1 divided by the square root of 4. Which means that the numerator is just 1 and the denominator is 2 (the square root of 4). But for the square root of (2/5) there's no easy simplification.
Square root of 2/5 Square root of 2 / square root of five. Multiply numerator and denominator by the square root of five. It equals the square root of ten / 5
Or if you are square rooting the entire thing then you make a common denominator and add them up. Then your answer is the square root of (13/20)
Oh yes. It is not simplest form to have a square root in the denominator if the grader is super picky. Azarah is right
Inside the square root symbol is also a quantity. Do for b you do 1/4 plus 1/25 and then simplify. For the other one it's the square root of 1/4 plus the square root of 1/25. I think
