Answer:

the answer is given below

Step-by-step explanation:

1st Question-

25% of that number is 9

let that number be X.

so according to the question;

25% of x is EQUAL to 9

we solve it by;

25/100×x=9

bring equation 25/100 to other side of =

so solving it;

9×100/25=x

x=9×4

x=36

so the answer is 36.

We will FACTORISE 729 by prime FACTORISATION method.

so by factorisation we obtain that;

729= 3×3×3×3×3×3

729=3⁶
