Answer:

a) x =18

b) x=2

c) x=3

Step-by-step explanation:

<u><em>Step(i):-</em></u>

a)

Given that (x-2)^{\frac{1}{4}  }

     put x = 18

   ⇒    (18-2)^{\frac{1}{4} } = (2^{4} )^{\frac{1}{4} } = 2

      (x-2)^{\frac{1}{4}  } =2    

b)

put x= 2

(1-x)^{\frac{1}{3}  } =  (1-2)^{\frac{1}{3}  } = (-1)^{\frac{1}{3} } = -1

 (1-x)^{\frac{1}{3}  } = -1

c)

put x=3

\sqrt{x^{2} +7} = \sqrt{3^{2} +7} = \sqrt{16} = 4

\sqrt{x^{2} +7}= 4

the population of a local species of dragonfly can be found using an infinite geometric series where a1=30 and the common ratio
diamong [38]
The sum of any geometric sequence (if it converges, r^2<1) is of the form:

s(n)=a(1-r^n)/(1-r), a=initial term, r=common ratio, n=number of terms...

s(n)=30(1-0.4^n)/(0.6)

s(n)=50(1-0.4^n)

Since r<1 the sum of the infinite series is just:

s=50
