Question

Step by step for each one plz

Answer 1

Answer:

a) x = 11, b) x = 2/5, c) x = 1/2

Step-by-step explanation:

a)

11 x 11 x 11 = 1,331

Therefore, the answer is x = 11

b)

Reduce the fraction by the highest number 64 and 1000 go into. (which is 8)

So it'll turn into $\sqrt[3]{\frac{8}{125} }$

Then reduce the fraction again, which will leave you with $\frac{2}{5}$

Therefore, x= 2/5

c)

Reduce the fraction using 27.

That will give you $x^{3} = \frac{1}{8}$

Then simplify the equation, which will give you $x=\frac{1}{2}$
