First you simplify the square root of -8, which is approximately -2.83. Subtract -2 by the square root of -8, and you'll get -4.83. Divide -4.83 by 2, and the answer should be -2.415 or -2.42. I'm not sure about this answer though.
Answer:
i can answer if you add the picture of the graphs:)
Step-by-step explanation:
10. x=y/6+1 11. x=-2g+r/2
(1/4ab)^-2
Remove negative exponent by rewritten the equation as (4ab)^2
AUse Product rule to get:
4^2a^2b^2
Now raise 4 to the second power to get:
16a^2b^2
The last answer is correct.
You can put the numbers where the variables are and do the arithmetic, or you can simplify the expression first. In the latter case, you have
(3a^(-2-(-1))b^(6-5)/2)^2 = (3a^(-1)b^1/2^2 = (3b/(2a))^2
= (3(-2)/(2(3)))^2 = (-1)^2 = 1
The value of the expression is 1.
