Vlad [161]

Answer:

a 1 over 25

Step-by-step explanation:

Problem Statement:

     What is the value of  \frac{5^{4} }{5 ^{6} } ?

To solve this problem, we must familiarize ourselves with the concept of exponents and rules that guides them.

Exponents are used by scientists to report higher orders of a number.

Such large and often recurring expression is usually made up of a base and an exponent value.

The exponent value is the power of the base;   for example, 4³ has 4 as its base and 3 as the exponent.

Several rules guides solving an exponent, to this problem, the most applicable one is :

                            \frac{x^{a} }{x^{b} }  =  x^{(a-b)}

                           \frac{5^{4} }{5 ^{6} }   =  5^{4-6}  

                                 = 5^{-2}

                                 = \frac{1}{25}                                  

Therefore the solution is 1 over 25

nekit [7.7K]

Answer:

11th revision

Step-by-step explanation:

The first revision is in 2018, and for each 3 years there is a new revision.

From 2018 to 2048, there are 30 years.

So to find how many revisions there are, we can divide the 30 years by the period of 3 years:

Number of revisions = total period / period per revision = 30 / 3 = 10 revisions.

As the year 2018 also has a revision, we have 10 + 1 = 11 total revisions.

So in 2048 there will be the 11th revision.
