Uhhh, dang. I thought I maybe had the answer, but I just got confused too
Can someone please help me with a couple of problems please? 4 square root 6 divided by square root 30 And then (2 square root 5 +3 square root 7)^2 I need the step by step on how to solve these please and thank you
By using the PEMDAS order of operations, we get 3(6+7) = 39.
The equation be 3(6+7) then the correct answer is 34.
<h3>What is PEMDAS order of operations?</h3>
The order of operations exists as a law that describes the proper sequence of stages for estimating a math expression. We can recognize the order utilizing PEMDAS: Parentheses, Exponents, Multiplication, Division (from left to right), Addition, and Subtraction (from left to right).
Given: 3(6+7)
By using the PEMDAS order of operations, we get
(6+7) = 13
Then we get
3(6+7) = 3
13
= 39.
Therefore, the value of 3(6+7) = 39.

Answer:
Step-by-step explanation:
I will show you by example. For the sin ratio, we have that the sin of the reference angle is equal to the side opposite the angle over the hypotenuse of the right triangle. We use this example for finding the ratio, knowing the angle:
found on your calculator. Because this is a special angle in a right triangle, we can also say, by looking at a 60 degree reference angle that the side across from the angle measures square root of 3, and the hypotenuse measures 2. So in terms of a radical,
![sin(60)=\frac{\sqrt{3} }{2}](https://tex.z-dn.net/?f=sin%2860%29%3D%5Cfrac%7B%5Csqrt%7B3%7D%20%7D%7B2%7D)
If we don't know the angle, we use the 2nd button on our calculator to find it. For example, if our problem looked like this:
,
we are asked what angle has a sin ratio of 1/2. We find this angle by pressing the 2nd button on our calculator, then the sin button and you will see this on your screen:
![sin^{-1}(](https://tex.z-dn.net/?f=sin%5E%7B-1%7D%28)
Enter either a .5 or a 1/2 after that open parenthesis and hit enter and you'll get the angle measure. That's how you use the inverses to solve for missing angles.
