Write each expression using positive exponents.?

Question

1. (-5)^-3
2. 4c^-2d
3. 4x(yz)^-2

4. 1/6^-18

Answer 1

[Note: a^(-b) = 1/(a^b)]

1. 1/(-5)^3
2. 4/c^(2d)
3. 4x/(yz)^2
4. 6^18

Answer 2

often talking: a^-b = a^(-a million*b) = (a^-a million)^b = (a million/a)^b = a million^b / a^b = a million / a^b. a million) 7^-8 = a million / 7^8 2) 10^-6 = a million / 10^6 3) 23^-a million = a million / 23^a million = a million / 23 4) (-5)^-2 = a million / (-5)^2 = a million / 5^2 = a million / 25 5) (-18)^-10 = a million / (-18)^10 = a million / 18^10 6) m^-ninety 9 = a million / m^ninety 9 7) (.a million)^-12 = (a million/10)^-12 = ((a million/10)^-a million)^12 = 10^12 8) c^-6 = a million / c^6 9) p^-5 = a million / p^5 10) g^-17 = a million / g^17 11) 5z^-4 = 5*z^-4 = 5 * a million / z^4 = 5 / z^4 12) 3t^-a million = 3*t^-a million = 3 * a million/t^a million = 3/t^a million = 3/t

Answer 3

1.) 1/(-5)^3

2.) 4/(c)^-2d

3.) 4x/(yz)^2

4.) 6^18

Answer 4

1. (-5)^-3 = -1/(5^3)
2. 4c^-2 d = 4d/(c^2)
3. 4x(yz)^-2 = 4x/((yz)^2)
4. 6^18
Solved!!!

Answer 5

1) 1/(-5)^3

2) 1/(4c)2d


3) 4c/(xy)^2

Answer 6

1.) (-5)^ -3

* everything is always over 1 so it would be:

(-5)^-3
--------
1

*then, u move the -3 to the other side of the fraction bar and moving it makes it positve.

(-5)
------
1^3

3.)

4x(yz)
------------
1^2
