Answer:
h^24
Step-by-step explanation:
h^12 divided by h^4 is h^8 according to the rule of exponent because if you divide the two terms that have the same base but different exponents, you have to subtract the exponent number. 12-4=8.
(h^8)^3 is h^24 because again according to the rule of exponent you have to multiply the two exponents together, and 8 * 3 is 24.
The simplified expression is h^24.
Add 1/4 by 1/6 and get 5/12 so then you have 7/12 with black hair.
Isolate x by subtracting 12 on both sides to get<em> x=3</em>. You can plug it in to check. Hopefully I helped. :)
The probability of not picking a green is 3/4. To get this answer you would add up the blue and black marbles, giving you an answer of 9. You would then put 9 over 12, which simplified would equal 3/4. Another way to find the answer is to take 1 and subtract 1/4 because 1/4 is the probability of green marbles. Hope this helps!! Have an amazing rest of your day!! :) <span />
