A. 80

B. 96

C. [tex]5\sqrt[5]{5}[/tex]

D. [tex]6\sqrt[5]{5}[/tex]

Which of the following is equal to the expression below tex160243frac15 tex A 80 B 96 C tex5sqrt55tex D tex6sqrt55tex class=

Respuesta :

160 = 2 x 2 x 2 x 2 x 2 x 5 = 2^5 x 5

243 = 3 x 3 x 3 x 3 x 3 = 3^5

So

(160 * 243)^1/5

= 5th root of (160 * 243)

= 5th root of (2^5 * 5 * 3^5)

= 2 * 3 * (5th root of 5)

= 6 * (5th root of  5)

Answer is D. 6 * (5th root of  5)

The resultant expression, equivalent to [tex](160*243)^{1/5}[/tex] is Option (D) [tex]6\sqrt[5]{5}[/tex]

Exponents and its properties -

An exponent refers to the number of times a number is multiplied by itself. It is represented as a number or letter written above and to the right of a mathematical expression called the base. It indicates that the base is to be raised to a certain power. x is the base and n is the exponent or power.

Represented as [tex]x^{n}[/tex]

What are some of the properties of exponents ?

  • [tex]x*x*x[/tex] ........ upto n times = [tex]x^{n}[/tex]
  • [tex](x^{n})^{1/n} = x[/tex]
  • [tex](x^{n}*y^{n} )^{1/n} = xy[/tex]

How to solve the given exponent problem to get the equivalent expression ?

Given expression is [tex](160*243)^{1/5}[/tex].

Now we are separating the expression,

160 = 2*2*2*2*2*5 = [tex]2^{5}*5[/tex]

243 = 3*3*3*3*3 = [tex]3^{5}[/tex]

∴ [tex](160*243)^{1/5}[/tex] =  [tex](2^{5}*5*3^{5})^{1/5}[/tex] = [tex]2*3*5^{1/5}[/tex] = [tex]6\sqrt[5]{5}[/tex]

Thus the equivalent expression is Option (C) [tex]6\sqrt[5]{5}[/tex]
