Mathematics

when someone says a number squared or cubed, or to the certain power, it means how many times you multiply the base number by itself that many times, for example

2²= 2 * 2

or 9³ = 9 x 9 x 9

a square root or cube root, is a harder to understand, but still somewhat simple, it basically means how many what number squared or cubed equals this number.

so for example the square root of 9 = 3 because 3 x 3=9

or cube roots for example ∛125= 5 because 5 x 5 x 5

So here is an example one for you. √81.

Ticket for football final selling well, on Thursday 4/7 of the tickets are sold, on Friday 1/4 of the tickets are sold, What fra
sergij07 [2.7K]

Answer:

5/28

Step-by-step explanation:

1/1 represents the whole amount of tickets.

4/7 are sold on Thursday.

an additional 1/4 are did on Friday.

fraction of available tickets on Saturday are therefore

1/1 - 4/7 - 1/4 = 4/1 - 16/7 - 1/1 = 28/1 - 16/1 - 7/1 = 5/1

that means out of 28 equal parts of the total number of tickets 16+7 = 23 parts have been sold.

so, there are only 5 out of the total 28 parts available on Saturday, and the fraction of available tickets is therefore 5/28.

we could have also tried to bring both fractions to the same denominator, and found that this is 28.

and then

4/7 + 1/4 = 4/4 × 4/7 + 7/7 × 1/4 =

= 16/28 + 7/28 = 23/28

and the whole is 28/28.

so we have 28/27 - 23/28 = 5/28 left.

surprise, surprise, it is the same result ...
