0.015625 is equal to 0.015625
It seem like it's listing the factors and not the roots. If the given factors are x-2, x-(1+sqrt(5)), and x+3i
Then this means that x-(1-sqrt(5)) is another factor. So it looks like choice B is the answer. I'm using the idea that if x-(a+b*sqrt(c)) is a factor then so is x-(a-b*sqrt(c)).
75% of n is 375.
Step-by-step explanation:
Given,
45% of a number n = 225
We will find n first.

Dividing both sides by 0.45

Now we have to find 75% of n.
75% of n = 
75% of n = 375
75% of n is 375.

Answer:
(12ab)^1/2
Step-by-step explanation:
(⁶√12ab)³
= [(12ab)^1/6]³
= (12ab)^(1/6 * 3)
