Hi, just need to know if my answer is right. If its wrong, can you please show me the steps. ( √5+√21 — √5—√21) ^2 FYI: 5+√21 is under one root...

thank you!

√7/y

Hi, I keep getting 2a+2b but that's not the answer. I need some help solving the equation in the title. Thanks

-5√48 + 4√108

√14m5√7m5 So, what I was taught is to multiply through, so 14*7 and m5*m5 which would give me √98m10 I don't know where to go from there. &nb...

Hi, please help me understand solving this I'm a little lost : (√2x+4 -1) (√2x+4 -1) Note: The 4 is under the root but the 1 is not.

I am having problems with subtracting radicals. e.g 3√2-√2

3√ 2x+5 -15=0 (-15 is not under the radical)

Basically, the file discusses how to increase a Calculus student's understanding by identifying and addressing unfilled gaps in their earlier...

7+ √3x = √5x+4 +5

How to work the problem it's a radical expression so "sqrt" is √ square root

It's about subtracting radicals and then simplifying them.

simplify

Good evening, I am in need of assistance working through this problem. It is an example in my text book, so it lists out the steps. The problem is that I ended up at the second to last...

I'm very confused about how to separate the variables, and the numbers, or when to move stuff to the outside of the radical.

Nina says that 16+4 (2) cannot be simplified. George says that is can be simplified to 20 (2). who is correct? Explain how you know. NOTE...

I know the answer is (3b^2c)/a but I don't know the steps.

A) (n-7)^2-25=0 B) (2r+3)^2=44

A) m^2-75=0 B) 3t^2=21
