I need help simplifying this radical expression

Step-by-step explanation:

We can simplify this radical expression by expanding the expression inside the radical:

is the same as:

since the exponents ultimately add up. This can be further simplified into:

, and since the 2 values are being squared, and the square root operation is the inverse of that, it cancels out:

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
