Factor completely 10x5 + 4x4 + 8x3.Prime
2(5x5 + 2x4 + 4x3)
2x3(5x2 + 2x + 4)
2x(5x4 + 2x3 + 4x2)

Answers

Answer 1

Answer:

Answer:

The second option is correct.

Step-by-step explanation:

The given expression is

$10x^5+4x^4+8x^3$

The factors of first term is

$10x^5=2* 5* x* x* x* x* x$

The factors of second term is

$4x^4=2* 2* x* x* x* x$

The factors of third term is

$8x^3=2* 2* 2* x* x* x$

The common factors are 2,x,x and x, therefore the greatest common factor is $2x^3$ .

$2x^3(5x^2+2x^2+4)$

Therefore the second option is correct.

Answer 2

Answer: 10x^5 + 4x^4 + 8x^3
2x^3 ((10x^5)/(2x^3) + (4x^4)/(2x^3) + (8x^3)/(2x^3))
2x^3(5x^2 + 2x + 4)

The answer is: 2x^3(5x^2 + 2x + 4).

Which expression is not equivalent to 6^3/6^6

Answers

The expression that is not equivalent to $6^3/(6^6)$ is $1/6^2$ (option A)

How to find the inequivalent expression?

The expression given is $6^3/(6^6)$

Using the law of exponent:

$(x^4)/(x^2) =x^(^4 ^- ^2^)$

$= x^2$

we can simplify the expression:

$(6^3)/(6^6) = 6^3^-^6$

Simplifying the exponent gives

$6^-^3$

This can also be expressed as a fraction:

$(1)/(6^3)$ or $(1)/(216)$

Comparing the options, we can see that the inequivalent expression is $1/6^2$ (option A)
