2 multiplied by (1/8)^1/3

Question

2 (1/8)^1/3

 

Answer 1

2 (1/8)^1/3

 

using BODMAS - Bracket(B) Of(O) Division(D) Multiplication(M) Addition(A) & Subtraction(S) 

 

we'll solve the Bracket first

 

(1/8)^1/3 = ³√(1/8)

 

but 1/8 = (1/2)³

 

So we'll rewrite it as;

 

³√(½)³

 

The cube root ³√ is cancelled out but cube ³

 

Thus we'll have (½)

 

Now remembering that the original equation was multiplied by 2,

 

we'd now have 2 * (½)

 

2/1 * (½) = 2/2

 

this results in 1.

 

 

Your final answer is 1.

 

Hope this helps. :-)
