UkoKoshka [18]

Answer: 57%

Step-by-step explanation:

Davis's monthly expenditure and his monthly salary was 3 : 7.

For every $7 received, he saved $4.

Percent = 4/7

= 57%

The expression is

(-5)^7\div  (-5)^2

To find:

The simplified form of the given expression so there is only one positive power for the baser -5.

Solution:

We have,

(-5)^7\div  (-5)^2

=\dfrac{(-5)^7}{(-5)^2}

Using the properties of exponents, the given expression can be written as

=(-5)^{7-2}                  [\because \dfrac{a^m}{a^n}=a^{m-n}]

=(-5)^{5}

Here, the base is -5 and the exponent is 5.

Therefore, the correct option is C.
