Question

please give me right answer and fast​

Answer 1

Answer:

4,3

Step-by-step explanation:

1536/4=324 it is 18 square

the sum of numbers should always divisible by 9 when the number is divisible by 9

so7+y+8=15+y

nearest number to 15 which is divisible by 9 is 18.

So y=3 because 15+y=18

y=18-15=3 if it helps please mark as brainliest answers

Answer 2

16.

$\text{\boxed{1536=2^9\times 3}}$

$\text{If the number is a cube, its multiplication can be divided into three equal groups.}$

The exponents of each factor should be a multiple of 3, to divide into.

The smallest factor is 3.

$\text{\underline{It is required that 1536 must be divided by the smallest number 3.}}$

17.

$\boxed{\text{Divisiblity test of 9 : Add all digits.}}$

Digit sum $7+y+8=y+15$

$\text{\underline{ As 15 is already a multiple of 3, the smallest value of y is 0}}$
