8 0

$\sqrt{a}=b\iff b^2=a\ for\ a\geq0\ \wedge\ b\geq0\\---------------------\\\\Method\ \#1:\\\\\sqrt{9\cdot4}=\sqrt{36}=6\ because\ 6^2=36\\\\d)\ \sqrt9\cdot\sqrt4=3\cdot2=6\\\\\sqrt9=3\ because\ 3^2=9;\ \sqrt4=2\ because\ 2^2=4\\\\Answer:\ \boxed{d)\ \sqrt9\cdot\sqrt4}\\\\Method\ \#2:\\\\\text{use}\ \sqrt{a\cdot b}=\sqrt{a}\cdot\sqrt{b}\\\\\sqrt{9\cdot4}=\sqrt9\cdot\sqrt4\\\\\text{Therefore your answer is}\ \boxed{d)}$

Simplify the expression. 12x^-6 y^10 times 3x^7 y

Vlada [557]

We need to simplify the expression:

$12x^{-6}y^{10} \times (3x^{7}y)$

Now, we know that we can resolve the exponents of the variables with the like terms only and we can multiply the coefficients independently:

Now,

$12x^{-6}y^{10} \times 3x^{7}y=(12 \times 3)\times (x^{-6}\times x^{7})\times (y^{10}\times y)$

On simplifying the above expression we get:

$36\times x^{(-6+7)}\times y^{(10+1)}$

$=36 \times x^{1}\times y^{11}$

$=36 \times x \times y^{11}$

$=36xy^{11}$

So the simplified form of the expression $12x^{-6}y^{10} \times 3x^{7}y=36xy^{11}$ .

If you have 9/10 of a pound of granola how many 1/5 pound bags can you fill ?

Lostsunrise [7]

Answer:

Step-by-step explanation:

1/5 is the same as 2/10. How many 2's can you put in 9? You can put 4.5 2's in a 9. However, filling half a bag does not fill the entire bag, so the answer would be 4. You can fill 4 full 1/5 pound bags with 9/10 pounds of granola.
