Example : 4 + 5 radical 3
How does that work??
And how do you divide the answer with 12?
(P.S made the problem up but that's the concept of what I don't get)
4+5^3 5 x 5 x 5 =125
125+4 = 129 129/12 = 1.75
all you gotta do is take it step my step... always remember PEMDAS
4 + 5 radical 3
= 4 + 5√3
= 4 + 5(1.7321)
= 12.6603
now if you want to divide that by 12, just do it
to get 1.055
To understand how to work with the expression 4 + 5√3, let's break it down step by step:
Step 1: Simplify the expression 5√3:
The expression 5√3 represents a number multiplied by the square root of 3. To simplify it, we need to find the value of √3.
√3 is an irrational number, which means it cannot be expressed exactly as a fraction or a decimal. However, we can approximate its value to 1.732 (rounded to three decimal places).
So, 5√3 ≈ 5 * 1.732 ≈ 8.66 (rounded to two decimal places).
Step 2: Add the simplified expression to 4:
Now that we've simplified 5√3 to approximately 8.66, we can add it to 4:
4 + 8.66 ≈ 12.66 (rounded to two decimal places).
This is the value of the expression 4 + 5√3.
Moving on to the second part of your question:
To divide the answer with 12, follow these steps:
Step 1: Divide 12.66 by 12:
12.66 ÷ 12 ≈ 1.055 (rounded to three decimal places).
This is the result of dividing 12.66 by 12.
So, the final answer would be approximately 1.055.
