Answer:

a)e^{3}e^{4}=e^{7}

b) (e^{3})^{4}=e^{12}

c) (e^{3})^{-2}=e^{-6}

d) e^{0}=1

Step-by-step explanation:

a) Here we can use the product of powers rule: x^{a}x^{b}=x^{a+b}

e^{3}e^{4}=e^{7}

b) In this ca we use power of a power rule: (x^{a})^{b}=x^{a*b}.

(e^{3})^{4}=e^{12}

c) We use the same rule above.

(e^{3})^{-2}=e^{-6}

d) Finally, we can use zero exponent rule: x^{0}=1.

e^{0}=1

I hope it helps!

franklin school has 3 boys for every 4 girls in the fifth grade. there are 140 students in the 5th grade. How many boys are ther
marin [14]

Answer:

There are 60 boys and 80 girls in Franklin School.

Step-by-step explanation:

"franklin school has 3 boys for every 4 girls in the fifth grade." means that the ratio of boys to girls is: 3:4

It can also be written as 3/4

Also given

Total number of students: 140

We will use ratios to find the number of boys and girls in shool.

First of all, we have to calculate the sum of ratio which is: 3+4 = 7

Let b be the number of boys and g be the number of girls

Then

b = \frac{Ratio\ of\ boys}{Sum\ of\ ratio} * Total\ students\\= \frac{3}{7} * 140\\= 3*20\\=60\\g = \frac{Ratio\ of\ girls}{Sum\ of\ ratio} * Total\ students\\g = \frac{4}{7}*140\\= 4*20\\=80

Hence,

There are 60 boys and 80 girls in Franklin School.
