Mathematics

Answer:

Step-by-step explanation:          

                                                                                       1

Given x³, we can write the equivalent expression -----------

                                                                                    x^(-3)

                                                              1

Given y^(-4) we can rewrite this as  ----------

                                                             y^4

Here we're applying the "rule of negative exponents."

vodka [1.7K]

Answer:

Let's assume the number be 100.

According to the problem , 100 is increased by 100%.

So, new number will be 100+100=200

Now 200 will decreased by 20%.

So, 20% of 200= 0.20*200= 40.

So, again the number has been changed into 200+40=240.

So, x=240
