The sum of two numbers is 17

Mathematics

Answer:

10 and 7

Step-by-step explanation:

Let the numbers be A and B

The sum of the two numbers is 17.

That’s

A + B = 17

The difference of the numbers is 3

A - B = 3

We now have two equations

1. A + B = 17

2 . A - B = 3

Subtract equation two from equation one.

B - - B = B + B = 2B

2B = 14

Divide both sides by 2

2B/2 = 14/2

B = 7

Now substitute 7 for B into either of the equations to get A.

Using equation 1 we have

A + B = 17

A + 7 = 17

Subtract 7 from both sides

A - 7 = 17 - 7

A = 10

The numbers are 10 and 7

Write (8a^-3)^-4/3 in simplest form. <br><br> Please show your work!
german

Answer:

(a/2) ^4  or a^4/16

Step-by-step explanation:

(8a^-3)^-4/3

split into two parts

8^ -4/3   *  (a^-3)^-4/3

using the power to the power rule we can multiply the exponents

8^(-4/3)  *a^(-3*-4/3)

8^ (-4/3) * a^(4)

replace 8 with 2^3

(2^3)^(-4/3) * a^(4)

using the power to the power rule we can multiply the exponents

2^(3*-4/3) * a^(4)

2 ^ (-4) * a^4

the negative exponent means it goes in the denominator if it is in the numerator

a^4/2^4

make a fraction

(a/2) ^4

or a^2/16
