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

-5√48 + 4√108

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.

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

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

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

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

7+ √3x = √5x+4 +5

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...

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...

It's about subtracting radicals and then simplifying them.

simplify

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

Kepler's third law, T = √(Kr3), can be used to calculate the time it takes for a planet to complete one orbit of a star. The average radius of the planet's orbit in km is r, and K is a constant...

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

the question is √x+3 = √2x+8 I squared both ends to get x+3= 2x+8 I moved the variables to one side and the numbers...

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