Describe how to simplify the expression (3^-6)/(3^-4). Answers: Divide the bases and then add the exponents. Keep the base the same and then add the exponents. Multiply the bases and then subtract the exponents. Keep the base the same and then subtract the exponents.

Answers

Answer:

Last option: Keep the base the same and then subtract the exponents.

Step-by-step explanation:

There is a property called "Quotient of power property".

This property states that if you need to divide two powers with the same base, you must keep the same base and subtract the exponents:

(a^m)/(a^n)=a^((m-n))

Then, you need to apply this property to the expression ((3^(-6)))/((3^(-4))) to simplify it.

Therefore, you get that the expression simplified is:

3^((-6-(-4)))=3^((-6+4))=3^(-2)

Ricky is filling an 8 inch by 4 1/2 inch rectangular box with packing peanuts. The peanuts are cubes that come in two different sizes ,1 cubic inch and 1/8 inch .How many peanuts of each size are needed to fill the box?

Answers

Ok, so we can fill the part of the box that corresponds to the 8x4 inches with the boxes that are 1 cubic inch - that wound be 8x4, that is 32 such boxes.

then the rest would be 8x (1)/(2) inches, that is 4 cubic inches.

In order to fill in 4 cubic inches with  (1)/(8) inches boxes we calculate:

4/ (1)/(8)=4*8=32  So it's also 32 such small boxes!
