Hello. I'm learning about simplying radicals and in one of the questions it has a variable to the second power like below:
1) square root of 28x^2
2) square root of 25x^2
3) square root of 80n^2
Can you answer at least one of them and explain what you did?
THANK YOU SO MUCH!!
can someone help me.. please?
well i think it's
1) 4x sq.root7
2) 5x
just basically sq. root them(for the exponent divide by the root(since its square root it's 2 you divide by)
THANK YOU!
Your answer is right I found it in class =)
thx again =D
Of course! I'd be happy to help you simplify one of the radical expressions. Let's start with the first one:
1) √(28x^2)
To simplify this expression, we want to break down the terms inside the radical into their simplest form.
First, let's observe that 28 can be factored into 2 * 2 * 7. We can rewrite the expression as:
√(2 * 2 * 7 * x^2)
Next, we want to identify perfect squares within the expression. In this case, x^2 is a perfect square since it can be written as (x)(x) or x^2. We can rewrite the expression as:
2x * √(2 * 7)
Now, we can simplify the expression further by evaluating the square root of 2 * 7, which is equivalent to √(14).
Therefore, the simplified form of the original expression √(28x^2) is:
2x√(14)
I hope this explanation helps! Let me know if you have any further questions.
