The sqare roots close to 94 are of 10 and 9
as 9*9=81
and 10*10=100

Answer:

$\frac{1}{4k^3}$

Step-by-step explanation:

It's already in a form that only ha positive exponents. Just to state it though you could rewrite it as $k*(4k^{4})^{-1}$ or $k*4^{-1}*k^{-4}$ The question asks for positive exponents though so yu don't need to do that.

You also need to know $\frac{x^a}{x^b}=x^{a-b}$ so in this case $\frac{k}{k^4}=\frac{k^1}{k^4} =k^{1-4}=k^{-3}=\frac{1}{k^3}$

so $\frac{k}{4k^4}=\frac{1}{4}*\frac{k}{k^4}=\frac{1}{4}*\frac{1}{k^3}=\frac{1}{4k^3}$

3rd Week: 15.33 - (1st Week + 2nd Week)

Solve:
6 1/4 + 4 2/3 = 10 8/12 or 10 2/3

15 1/3 - 10 2/3
14 4/3 - 10 2/3

4(4x−8)+4(3x−7)=7(2x+5)+6]\<br><br><br> I NEED HELP FAST!!!!

Deffense [45]

The answer you are looking for is $7\frac{101}{14}$ .

Explanation:

4(4x−8)+4(3x−7)=7(2x+5)+6

Step 1: Simplify both sides of the equation.

4(4x−8)+4(3x−7)=7(2x+5)+6

(4)(4x)+(4)(−8)+(4)(3x)+(4)(−7)=(7)(2x)+(7)(5)+6(Distribute)

16x+−32+12x+−28=14x+35+6

(16x+12x)+(−32+−28)=(14x)+(35+6)(Combine Like Terms)

28x+−60=14x+41

28x−60=14x+41

Step 2: Subtract 14x from both sides.

28x−60−14x=14x+41−14x

14x−60=41

Step 3: Add 60 to both sides.

14x−60+60=41+60

14x=101

Step 4: Divide both sides by 14.

14x

101
