Answer:

\frac{a^{2} }{b}

Step-by-step explanation:

Given expression:

           ( a⁶ b⁻³)^{\frac{1}{3} }

Find an expression equivalent to this;

 To solve this problem, we have to expand the parentheses by using one of rule of exponents.

          (a x b)ⁿ   = aⁿ x bⁿ

 So;

      ( a⁶ b⁻³)^{\frac{1}{3} }  =  a⁶^{\frac{1}{3} } x b⁻³ ^{\frac{1}{3} }

                      = a² x b⁻¹

  Therefore ( a⁶ b⁻³)^{\frac{1}{3} }  = \frac{a^{2} }{b}

PLEASE HELP WILL GIVE BRAINLIEST the number of students at north middle school is 1240 and is decreasing by 25 students per year
Nikolay [14]

Answer:

-88

Step-by-step explanation:

Let N(x) be the number of students at NMS for a certain number of years.

Let S(x) be the number of students at SMS for a certain number of years.

Let x be the number of years.

N(x)=1240-25x

S(x)=800-30x

When # of students is equal, N(x)=S(x). Therefore, we are looking for the value of x (# of years) when 1240-25x=800-30x

Subtract 1240 from each side

-25x=-440-30x

Add 30x

5x=-400

x=-88 years
