Simplify the following:
((8 x^3 y^2 a^2 b^4)/4)^(-2)
8/4 = (4×2)/4 = 2:
(2 x^3 y^2 a^2 b^4)^(-2)
Multiply each exponent in 2 x^3 y^2 a^2 b^4 by -2:
(x^(-2×3) y^(-2×2) a^(-2×2) b^(-2×4))/(2^2)
-2×3 = -6:
(x^(-6) y^(-2×2) a^(-2×2) b^(-2×4))/2^2
-2×2 = -4:
(y^(-4) a^(-2×2) b^(-2×4))/(2^2 x^6)
-2×2 = -4:
(a^(-4) b^(-2×4))/(2^2 x^6 y^4)
-2×4 = -8:
b^(-8)/(2^2 x^6 y^4 a^4)
2^2 = 4:
Answer: 1/(4 x^6 y^4 a^4 b^8) thus the answer is A
I think it’s width but I’m not sure
Let P be the cost of pucks, S the cost of sticks.
1.5p+3s=23
2.5p+s=20
subtract eqn 2 from 1,we get
5p+3s-5p-s=23-20
2s=3
s=3/2=1.50
Then from eqn 2,
5p+3/2=20
5p=40/2-3/2
p=37/10=3.70
Therefore,pucks cost $3.70 and sticks cost $1.50
Jason will need to use 9 more 1/3 gallon-ful pitchers to fill the rest of the empty 3/4 gallon water jug. You convert the two fractions so they have the same denominator (1/12 and 3/12). Then you add the remaining amount of 1/12's to complete 12/12, or 1.
