Question

simplify
z^5x^3/z^4x

Answer 1

@jdoe0001

Answer 2

\(\bf \cfrac{z^5x^3}{z^4x}\implies \cfrac{z\cancel{ zzzz}xx\cancel{ x}}{\cancel{ zzzz}\cancel{ x}}\)

Answer 3

or you could do it as explained before
but subtracting the exponents, would give the same

Answer 4

so x^2?

Answer 5

I mean zx^2

Answer 6

well, yes
but youi're mising a "z" there
let us see using the negative exponents

\(\bf a^{-{\color{red} n}} \implies \cfrac{1}{a^{\color{red} n}}\qquad \qquad

\cfrac{1}{a^{\color{red} n}}\implies a^{-{\color{red} n}}
\\ \quad \\
\\ \quad \\ \quad \\

\cfrac{z^5x^3}{{\color{brown}{ z^4x}}}\implies z^5x^3{\color{brown}{ z^{-4}x^{-1}}}\implies z^5{\color{brown}{ z^{-4}}}x^3{\color{brown}{ x^{-1}}}
\\ \quad \\
z^{5-4}x^{3-1}\implies zx^2\)

yeap

Answer 7

write (2b)^3 without exponents

fill in the blank (2b)^3 =

Answer 8

\(\large \bf (ab)^n\implies a^nb^n\)

Answer 9

so you pretty much just, distribute the exponent

Answer 10

so 222bbb? but what about the second part? is it 8b^3?

Answer 11

\(8b^3\) is correct

Answer 12

what about the first part was that right?

Answer 13

yes.... you could expand it to 2*2*2*b*b*b
but the "simplified" version would be \(8b^3\)

Answer 14

can you help me with a few more?

Answer 15

sure, tis easier posting anew though
more eyes, thus if I dunno, someone else may
and we can revise each other :)

Answer 16

ok :-)
