Answer:

D

Step-by-step explanation:

$(a^{m})^{n}= a^{m*n}\\\\\\(\frac{3^{4}}{7^{3}})^{3}=\frac{(3^{4})^{3})}{(7^{3})^{3}}\\\\=\frac{3^{3*4}}{7^{3*3}}\\\\=\frac{3^{12}}{7^{9}}$

A bakery made some cookies. 1/2 of the cookies were placed in large boxes. 3/7 of the cookies were placed in small boxes . The r

saul85 [17]

Answer:

378 cookies

Step-by-step explanation:

Let total amount of cookies be y

Let amount of cookies in each small box = x

let amount of cookies in each large box = x + 32

Therefore total amount of cookies in 18 small boxes = 18x

Total amount of cookies in 7 large boxes = 7(x+18) = 7x + 126

Fractional amount of cookies in small & large boxes = 1/2 + 3/7 = 13/14

Total amount of cookies in small & large boxes = 18x + 7x + 126 = 25x + 126

Fractional amount of small cookies equals amount of small cookies in 18 boxes.

3/7y = 18x------------------Eqn 1

From eqn above y = 42x

Equating fractional sum & total sum =

25x + 126 = (13/14)y

Upon cross multiplication

350x + 1764 = 13y---------Eqn 2

Substituting y = 42x into equation 2

350x +1764 = 13(42x)

1764 = 546x - 350x

1764 = 196x

x = 9 cookies

Therefore total number of cookies = 42 × 9 = 378 cookies

What is equivalent to 5^3 ( Choose all that apply)

Tema [17]

Answer:

A, and D

Step-by-step explanation:

A works because when you multiply like bases, you add exponents, so we have...

5^7*5^-4 = 5^(7+(-4)) = 5^(7 -4) = 5^3

B doesn't work because when you divide like bases, you subtract the exponent of the denominator from the exponent of the denominator...

5^12/5^4 = 5^(12 - 4) = 5^8

C doesn't work because there is addition.

5 + 5² = 5 + 25 = 30, and 5³ = 125

D works because 5^0 = 1, so we have

5^0(5^3) = 1(5^3) = 5^3

E doesn't work because there is subtraction...

5^3 - 5^0 = 5^3 - 1 = 124
