<h3><u>
Answer:</u></h3>
87 is your answer.
<h3><u>
Step-by step solution:</u></h3>
Step 1: <em>According to the DMAS rule, simplify the values that are inside the brackets.</em>
- => [(8 - 2) x (3 + 2) - 1] x 3
- => [(6) x (5) - 1] x 3
- => [6 x 5 - 1] x 3
- => [30 - 1] x 3
- => 29 x 3
Step 2: <em>According to the DMAS rule, next, simplify the values that are having multiplication.</em>
<h3><u>
Final Answer:</u></h3>
Therefore, 87 is your answer.
Hoped this helped.
Let's plug in 2 as "n" as it is greater than one.
So it should be the absolute value of ((1/2) +(7/8)i)^2
Let's evaluate the equation,
((1/4)+(7i/8)+(49/64)i^2)
Now, the definition of "i" is that when you square it, you get negative one as the answer.
Now plug that in and you get,
((1/4)-(49/64)+(7i/8))which is equal to: (-33/64)+(7i/8)
But we aren't done just yet!
Since there is an absolute value, it is the same thing as the square root of ((-33/64)^2)+(7/8)^2) Which is (65/64)^2 and square root it and it is 65/64. So it is therefore A.
