PLS HELP HAS TO BE CORRECT

Answer:

○ 4⁵\4²

Step-by-step explanation:

1. According to the Quotient-to-Power Exponential Rule, whenever you divide terms with exponents and coefficients, you subtract the exponents:

4²\4⁵ = 4⁻³

3. According to the Negative Exponential Rule [Reverse], you bring the denominator to the numerator while ALTERING THE INTEGER SYMBOL FROM POSITIVE TO NEGATIVE:

b⁻ⁿ = 1\bⁿ

However, according to the Negative Exponential Rule, you bring the denominator to the numerator while ALTERING THE INTEGER SYMBOL FROM NEGATIVE TO POSITIVE:

bⁿ = 1\b⁻ⁿ

Anyway, this is what you get using this exponential:

1\4³ = 4⁻³

4. Back to what I said about the <em>Quotient-to-Power</em> Exponential Rule, you subtract the exponents, but in this case, doing that will give you 4³. This is the ONLY uniqueness, while the rest of them are 4⁻³.

I am joyous to assist you anytime.

NNADVOKAT [17]

Answer: Fraction of paint used for bird house = $\dfrac14$

Step-by-step explanation:

Let quantity of the total paint be 1.

Given: Fraction of paint to book shelf = $\dfrac38$

Fraction of Paint to leg = $\dfrac14$

Fraction of Paint left = $\dfrac18$

Let x= fraction of paint used for bird house.

Total paint = $\dfrac38 +\dfrac 14+\dfrac18+x=1$

$\Rightarrow\ \dfrac{3+2+1}{8}+x=1\\\\\Rightarrow\ \dfrac{6}{8}+x=1\\\\\Rightarrow\ x=1-\dfrac68\\\\\Rightarrow\ x=\dfrac{2}{8}=\dfrac14$

So, Fraction of paint used for bird house = $\dfrac14$

Cell phone plan A costs 79 per month and comes with a free 500 phone. Cell phone plan B costs 50 per month but does not come wit

meriva

Answer: it will take 25 months

Step-by-step explanation:

Let x represent the number of months that it will take for the cost of both plans to be the same.

Cell phone Plan A costs $70 per month and comes with a free $500 phone. This means that the total cost of x months with plan A would be

70 × x = $70x

Cell phone plan B costs 50 per month but does not come with a phone. If you buy the 500 phone and choose plan B, then the total cost of x months with plan B would be

500 + 50 × x = 500 + 50x

To determine the number of months until your cost is the same as Plan A's, we would equate both costs. It becomes

70x = 500 + 50x

70x - 50x = 500

20x = 500

x = 500/20 =25
