(3y^0 x^2)^6 times y^-3 zx8

timurjin [86]

Ok so some basic rules

$(x^m)(x^n)=x^{m+n}$
$(ab)^c=(a^c)(b^c)$
$(x^m)^n=x^{mn}$
$x^0=1$
$x^{-m}= \frac{1}{x^m}$

so
$[(3y^0x^2)^6][y^{-3}zx^8]$
$[(3(1)x^2)^6][y^{-3}zx^8]$
$[(3x^2)^6][y^{-3}zx^8]$
$[(3^6)((x^2)^6)][y^{-3}zx^8]$
$[(3^6)(x^{12})][y^{-3}zx^8]$
$(3^6)(x^{12})(y^{-3})(z)(x^8)$
$(3^6)(x^{12})(x^8)(y^{-3})(z)$
$(3^6)(x^{20})(\frac{1}{y^3})(z)$
$\frac{3^6x^{20}z}{y^3}$
$\frac{729x^{20}z}{y^3}$

Please help me with this question, image attached

Answer:

$W=(x-6)\ m$

Step-by-step explanation:

we know that

The area of rectangle is equal to

$A=LW$

we have

$A=(x^{2} -11x+30)\ m^2$

$L=(x-5)\ m$

substitute the given values in the formula of area

$(x^{2} -11x+30)=(x-5)W$

Remember that

$x^{2} -11x+30=(x-5)(x-6)$ ----> by completing the square

substitute

$(x-5)(x-6)=(x-5)W$

Simplify

$W=(x-6)\ m$
