Answer:
6
Step-by-step explanation:
scale factor is 0.25
so
∴ x = 1.5 ÷ 0.25 = 6
675=27(25)
=3*3*5*5 = 3^2*5^2 answer

Answer:
A
Step-by-step explanation:
Begin with Euler's formula. I am assuming youre aware of this if youre taking complex algebra? You can prove Euler's formula by doing a Maclaurin expansion of cosine, sine, and e^x. Euler's formula states that:

We can put the first complex number in exponetial form by noticing the input is 2pi/3. The second complex number has an input of pi/3. Therefore:


Then:

Simplify the coefficients to get:

When you divide exponentials, you subtract the exponents. Therefore:

Put it back into trigonemtric form using Euler's formula:

Cosine of pi/3 is 0.5, and sine of pi/3 is square root of 3 over 2. We have:
