Question

5x^6 * (-3x^3) help I will medal

Answer 1

5x6(−3x3)


$\mathrm{Remove\:parentheses}:\quad\left(-a\right)=-a$Remove parentheses: (−a)=−a

$=-5x^6\cdot\:3x^3$=−5x6· 3x3



$\mathrm{Multiply\:the\:numbers:}\:5\cdot\:3=15$Multiply the numbers: 5· 3=15

$=-15x^6x^3$=−15x6x3



$\mathrm{Apply\:exponent\:rule}:\quad\:a^b\cdot\:a^c=a^{b+c}$Apply exponent rule: ab· ac=ab+c

$x^6x^3=\:x^{6+3}=\:x^9$x6x3= x6+3= x9

$=-15x^9$=−15x9

Answer 2

Is this right?

Answer 3

yes

Answer 4

i just anwsered this

Answer 5

$5x^6\left(-3x^3\right)$5x6(−3x3)


$\mathrm{Remove\:parentheses}:\quad\left(-a\right)=-a$Remove parentheses: (−a)=−a

$=-5x^6\cdot\:3x^3$=−5x6· 3x3



$\mathrm{Multiply\:the\:numbers:}\:5\cdot\:3=15$Multiply the numbers: 5· 3=15

$=-15x^6x^3$=−15x6x3



$\mathrm{Apply\:exponent\:rule}:\quad\:a^b\cdot\:a^c=a^{b+c}$Apply exponent rule: ab· ac=ab+c

$x^6x^3=\:x^{6+3}=\:x^9$x6x3= x6+3= x9

$=-15x^9$=−15x9

Answer 6

Yes I know @usercode3rror but I cannot understand what you said.

Answer 7

=−​15x9

Answer 8

5x6(−3x3)
=−5x6· 3x3
−15x6x3\
$=-15x^9$=−​15x9

Answer 9

HERE I will explain it in simple words.

Multiply the "normal sized letters" together. 5 * -3

and add the exponents.

5 * -3 is what?

6 + 3 is what?

Answer 10

britt i gave the anwser

Answer 11

good job @usercode3rror

Answer 12

;]

Answer 13

;)

Answer 14

For those of you who are confused at what @usercode3rror said, he basically said multiply the numbers, and add the exponents.

3 * -5 = -15

6 + 3 (these are the exponents) = 9

so...

-15x^9

Answer 15

Now that I look at what you said @usercode3rror I can understand it...my computer didn't load everything you had said lol

Answer 16

lol
