It is 9. You have to add 33y, then divide by 11 and you get x = 3y + 9
Answer:
x^(5/6) + 4(x^(7/3))
Step-by-step explanation:
Simplify x to the 1/3 power MULTIPLIED BY (x to the 1/2 power + 2x to the 2 power )
Simplify x^(1/3) × (x^(1/2) + (2x)^2)
= x^(1/3)(x^(1/2)) + x^(1/3)((2x)^2)
= x^(1/3+1/2) + 4(x^(1/3+2))
= x^(5/6) + 4(x^(7/3))
x^(1/3) is y such that y^3 = x
(x^(1/3) × x^(1/3) × x^(1/3)) = x^(1/3+1/3+1/3) = x^1 = x
x^(1/2) = √2 = y such that y^2 = x
(2x)^2 = 4x^2
Answer:
The answer is c
Step-by-step explanation:
The middle problem is adding, the others are taking away, so C is the correct answer
Answer:
(a) 0.018 dm^3
(b) 20 x 10^15 ml^3
Step-by-step explanation:
a) 18 cm^3 to dm^3
1 cm = 0.1 dm
So,
1 cm^3 = 0.001 dm^3
So, 18 cm^3 = 18 x 0.001 dm^3 = 0.018 dm^3
b) 20 hl^3 to ml^3
1 hl = 100000 ml
So, 1 hl^3 = 10^15 ml^3
So,
20 hl^3 = 20 x 10^15 ml^3.
