4.	Write the following cube in expanded form:[x-2/3y]^3
Answer» Answer: Step-by-step explanation we NEED to use (a-b)^3 formula here: we know ; (a-b)^3 = a^3 - b^3 - 3AB(a-b) in this case a= X b= 2/3y so by substituting terms we get, x^3 - (2/3y)3 - 3x*2/3y( x-2/3y) = x^3 - 8/27y3 - 2x/y(x-2/3y) if you want to expand further, we get, x^3 -8/27y^3 - 2x/y(x) - 2x/y(2/3y) = x^3 - 8/27y^3 - 2x^2/y - 4x/3y2 thank you and have a NICE day :)

4.

Write the following cube in expanded form:[x-2/3y]^3

Answer»

Answer:

Step-by-step explanation

we NEED to use (a-b)^3 formula here:

we know ; (a-b)^3 = a^3 - b^3 - 3AB(a-b)

in this case a= X

b= 2/3y

so by substituting terms we get,

x^3 - (2/3y)3 - 3x*2/3y( x-2/3y)

= x^3 - 8/27y3 - 2x/y(x-2/3y)

if you want to expand further, we get,

x^3 -8/27y^3 - 2x/y(x) - 2x/y(2/3y)

= x^3 - 8/27y^3 - 2x^2/y - 4x/3y2

thank you and have a NICE day :)

Answer» If any NUMBER ends with the DIGIT 0, it should be divisible by 10 or in other words, it will also be divisible by 2 and 5 as 10 = 2 × 5 Prime factorisation of 6n = (2 ×3)n It can be observed that 5 is not in the prime factorisation of 6n. Hence, for any VALUE of n, 6n will not be divisible by 5. Therefore, 6n cannot END with the digit 0 for any natural number n.

Check whether 6power n end with digit 6

Answer»

If any NUMBER ends with the DIGIT 0, it should be divisible by 10 or in other words, it will also be divisible by 2 and 5 as 10 = 2 × 5

Prime factorisation of 6n = (2 ×3)n

It can be observed that 5 is not in the prime factorisation of 6n.

Hence, for any VALUE of n, 6n will not be divisible by 5.

Therefore, 6n cannot END with the digit 0 for any natural number n.

Answer»

Step-by-step explanation:

For question 6:

tan 8 + tan 2+ tan 8 tan 28 = 1

tan 8 + tan 2 = 1- tan 8 tan 28

Dividing throughout by 1-tan 8 tan 28

$\frac{tan \: 8 \: + \: tan \: 28}{1 - tan \: 8 \: tan \: 28} = 1 \\ tan \: (8 + 28) = 1 \\ tan \: 36 = 1$
