Which are sums of perfect cubes? Check all that apply. 8x6 + 27 x9 + 1 81x3 + 16x6 x6 + x3 27x9 + x12 9x3 + 27x9

Over [174]

<u>Answer</u>:

Sums of perfect cubes are

$8x^6 + 27x^9 + 1$

$x^6 + x^3$

$27x^9 + x^{12}$

<u>Step-by-step explanation:</u>

Option (1) $8x^6 + 27x^9 + 1$

This can be written as

$2^3 (x^2)^3 + 3^3(x^3)^3 +1^3$

All the terms in the expression are can be represented as perfect cubes

Option (2) $81x^3 + 16x^6$

This can be written as

$9^2 x^3 + 4^2 (x^2)^3$

In this , all the terms are not perfect cubes , some of them are squares

Option (3) $x^6 + x^3$

This can be written as

$(x^2)^3 + x^3$

All the terms in the expression are perfect cubes

Option (4) $27x^9 + x^{12}$

This can be written as

$3^3(x^3)^3 + (x^{4})^3$

All the terms in the expression are perfect cubes

Option (5) $9x^3 + 27x^9$

This can be written as

$3^2x^3 + 3^3(x^3)^3$

In this , all the terms are not perfect cubes , some of them are squares too

Which choice are equivalent to the expression below? Check all that apply

ASHA 777 [7]

Answer:

A, B, and E apply

Step-by-step explanation:

One thing we can do is to make everything in the same format, under one square root, with no non-square roots.

First, we can say that 6 is equal to √36 as 6² =36, and 6 ≥ 0. Therefore, 6√3 = √36 * √3 = √108

For A, √3 * √36 = √108, so this applies

For B, √18 * √6 = √108, so this applies

For C, 108² = √something bigger than 108 = √11664, so this does not apply

For D, √54 ≠ √108, so this does not apply

For E, √108 = √108, so this applies

For F, √3 * √6 = √18, so this does not apply
