Last question and then I’ll take care of the rest on my own ^^^^
Bond [772]

Answer:

  (c)  5/2

Step-by-step explanation:

The applicable rules of exponents are ...

  (a^b)(a^c) = a^(b+c)

  (a^b)/(a^c) = a^(b-c)

  a^-b = 1/a^b

__

Using these rules, we can simplify the expression as follows:

  (5^-3)(2^2)(5^6)/((2^3)(5^2)) = (5^(-3+6-2))(2^(2-3)) = (5^1)(2^-1)

  = 5/2

Olenka [21]

Answer: Third option.

Step-by-step explanation:

In order to solve the given exercise it is important to remember that:

1. Rational numbers are defined as those numbers that can be wrriten as a  simple fraction.

2. The symbol for Rational numbers is: Q

3. Integers can be positive numbers, negative numbers and zero.

4. The symbol for Integers is: Z

5. Fractions have the following form:

\frac{a}{b}

Where:

 "a" is the numerator and "b" is the denominator.

The numerator "a" and the denominator "b" are both Integers ( and b\neq 0)

Therefore, based on the information given above, you can conclude that Rational numbers are numbers of the form \{\frac{a}{b}|a,b ∈ Z,b\neq0\}

Evaluate each expression for g = -7 and h = 3 and match it to its value. 1. g + h 2 2. g - h 46 3. h - g -21 4. gh -4 5. g + h2
Ivanshal [37]

Answer:

1. -4

2. -10

3. 13

4. -21

5. 2

6. 46

Step-by-step explanation:

To evaluate the expression, substitute g= -7 and h = 3. Then simplify using order of operations.

1.  g-h = -7 + 3 = -4

2. g-h = -7 - 3 = -10

3. h-g = 3 - -7 = 3+10 = 13

4.gh = -7(3) = -21

5. g+h^2 = -7 + 3^2 = -7+9 = 2

6. g^2-h = (-7)^2 -3 = 49 -3 = 46
