Answer:
0
Step-by-step explanation:
10 to the power of 0, is equivalent to 0. Since their is no given value, it is saying "226÷0" which equals 0.
Answer:
60%
Step-by-step explanation:
The original was $20 to $12, so if you divide both prices by 2 (to make one side 10 and the other the simplified percentage) you get:
10 to 6.
Percentages are typically x% out of 100, so if you multiply both by 10 you get:
100 to 60. All you have to do now is change the format to percentage instead of a fraction (60/100) and the answer is 60%.

Answer:
yawwwwwwnnn......,....done
Roots are the same as zeros, and you find them by factoring and solving for y. This one is easiest if done by "taking roots" method. Let's move the 176 over to the other side and then divide both sides by 4 to get the x^2 alone. If we do that have we get x^2 = -44. But we know that we cannot take the square root of a negative number without accounting for it by using the imaginary "i". Since "i" is equal to -1, let's rewrite that [sqrt-44] as [sqrt(-1)(44)]. Now let's simplify the 44 by finding its perfect square hidden in there: [sqrt(-1)(4)(11)]. Now, because -1 = i^2, we can rewrite that as well like this:
[sqrt(i^2)(4)(11)]. Both the i^2 and the 4 are perfect squares so that's what we pull out, leaving the 11 inside for an answer of x = +/- 2i[sqrt(11)]
