Q. Use the imaginary number i to rewrite the expression below as a complex number. Simplify all radicals. −52
Breakdown of −52: First, let's break down −52 into −1 and 52 to separate the negative sign which is associated with the imaginary unit i.−52=−1×52
Rewrite using i: Now, we know that −1 is the imaginary unit i, so we can rewrite the expression using i.−1×52=−1×52=i×52
Simplify 52: Next, we simplify 52. The number 52 can be factored into 4×13, where 4 is a perfect square.52=4×13=4×13=2×13
Combine i with radical: Now, we can combine the i from the imaginary unit with the simplified radical.i×52=i×2×13=2i×13
Write as complex number: Finally, we write the expression as a complex number, which is in the form a+bi, where a is the real part and b is the imaginary part. Since there is no real part in this expression, it's just the imaginary part.2i×13=2i13
