There's no way to begin until we know the value of ' i ' .
If ' i ' doesn't represent √-1 , then we can stop here
and discard the question as unanswerable.
If ' i ' is the famous √-1 , then here's how i⁵⁰ can be simplified:
Notice the following:
-- The 1st power of i is √-1 .
-- The 2nd power of i is (√-1)² = -1
-- The 3rd power of i is -√-1
-- The 4th power of i is (-√-1)·(√-1) = -(-1) = 1 .
-- Every 4 powers of ' i ' brings you back to ' 1 '.
So from the exponent of 50, you can knock out
the largest possible multiple of 4 , and evaluate
what's left.
50 = 48 + 2
i⁵⁰ = i² = -1 .
let grapes be x and kiwi be y:
a. coefficients here are 2.19 and 3.09 and they represent the price.
b. terms are and and they represent what she had spent on grapes and kiwi in total.
You can isolate the variable by subtracting 6 from both sides.
e.g.
x + 6 = 13
- 6 - 6
Now we have x = 7, which not only isolates the variable but solves for x.
If you don't know why we can subtract from both sides, look up the Addition Property of Equality and Subtraction Property of Equality.
