3/4 hr=60 times 3/4=45mins
45/6=7.5 letters
that is pretty slow if you ask me

1/4 times what=5/6
times 4/1 both sides
what=20/6
what=10/3
about 3 and 1/3 of the 1/4 in the 5/6

20mins=1/3hr so
1/3 times what=3.4
times 3/1 both sides
what=10.2
there are 10.2 of them

1yd=36in
3/4 times 36=27in
27/3=9
9 of them

16oz=1lb
3/4 times 16=12oz
12/2=6

Answer:

the correct option is C i.e. $8x^4yz^4\sqrt{2yz}$

Step-by-step explanation:

We need to solve the expression :

$\sqrt{128x^8y^3z^9}$

Factors of 128 are: 2x2x2x2x2x2x2

and we know √ = 1/2

and √a.b = √a.√b

Solving:

$=\sqrt{128x^8y^3z^9}\\\\=\sqrt{128} \sqrt{x^8} \sqrt{y^3} \sqrt{z^9}\\=\sqrt{2x2x2x2x2x2x2}\sqrt{x^8} \sqrt{y^2.y} \sqrt{z^8.z}\\=\sqrt{2^2x2^2x2^2x2}\sqrt{x^8} \sqrt{y^2.y} \sqrt{z^8.z}\\=(2^2)^{1/2} (2^2)^{1/2}(2^2)^{1/2} (2)^{1/2} (x^8)^{1/2} (y^2)^{1/2} (y)^{1/2} (z^8)^{1/2} z^{1/2}\\=2.2.2.(2)^{1/2}x^4y(y)^{1/2}z^4(z)^{1/2}\\=8x^4yz^4\sqrt{2yz}$

So, the correct option is C i.e. $8x^4yz^4\sqrt{2yz}$
