Answer:

Step-by-step explanation:

Rule: a Minus power always goes to the opposite place to where it is. If it is in the denominator, it goes to the numerator. If it is the numerator, it goes to the denominator. The minus power does not affect the sign of the expression.

So you are right. The minus power does not give a minus answer.

$\dfrac{y^{-2}}{3y^4}=\dfrac{1}{3y^2y^4}=\dfrac{1}{3y^{(2 + 4)}} = \dfrac{1}{3y^6}$

Answer: A

Vivi is a drummer for a band. She burns 756 calories while drumming for 3 hours. She burns the same

german

The question you asked uses the concept of division, something that a bit tricky at first but gets easier as you master it!

So first let’s write and equation for your problem:

Let x = the amount of calories she burns each hour.

So we already know that Vivi was drumming for 3 hours, that she burned 756 calories, and that she burned the same amount of calories each hour.

Since she burned 756 calories in total, we know that the equation will have to equal 756:

= 756

We also know that the answer will be 3(hours) times x(the amount of calories), so now we just plug it into the equation:

3x = 756

To find what ‘x’ equals we have to divide both side by 3:

3x/3 = 756/3

Now all we have to do is simplify and you have your answer!

x = 252

And there you have it, Vivi burned 25 calories per hour!

Hope this helps! :)

What is 1/144 as an expression using a negative exponent

MrRissso [65]

ANSWER

${12}^{ - 2}$

EXPLANATION

The given expression is

$\frac{1}{144}$

This is the same as:

$\frac{1}{12 \times 12}$

In index notation, we write this as

$\frac{1}{ {12}^{2} }$

To write this as a negative index, we use the property:

$\frac{1}{ {a}^{m} } = {a}^{- m}$

This implies that;

$\frac{1}{ {12}^{2} } = {12}^{ - 2}$
