Answer:

74 weeks

Step-by-step explanation:

Given :

Let x = number of weeks

Gallon A:

Capacity = 666

Leak rate = 4 gallons per week

666 - 4x

Gallon B:

Capacity = 888

Leak rate = 7 gallons per week

888 - 7x

666- 4x = 888 - 7x

666 - 888 = - 7x + 4x

-222 = - 3x

x = 222 / 3

x = 74

After 74 weeks

<h3>What is an integer exponent?</h3>

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

It is given that:

The expression:

= \rm (\dfrac{x^4a^2b^3}{x^{-2}ab^2})^3

After using the integer exponent property:

\rm =\dfrac{x^{12}a^6b^9x^6}{a^3b^6}

= a³b³x¹⁸ Or

=x¹⁸a³b³

Thus, the simplification form of the provided expression is x¹⁸a³b³ option

(d) x¹⁸a³b³ is correct.
