Plz help... again I just can’t

Answer:

$\frac{1}{6}$

Step-by-step explanation:

Because we are looking for the scale factor of the model to the bridge (model first), the scale factor will be less than one.

$\frac{5}{30}=\frac{1}{6}$

$\frac{6}{36} =\frac{1}{6}$

$\frac{9}{54} =\frac{1}{6}$

Each fraction ( $\frac{model}{bridge}$ ) can be simplified to $\frac{1}{6}$ . Therefore, the scale factor of the model to the bridge is $\frac{1}{6}$ .

Simplify the expression.

denis23 [38]

Answer:

option d

Step-by-step explanation:

$\sf \boxed{a^m*a^n = a^{m+n}\\\\}$

$\sf \left(\frac{m^{-1}m^{5}}{m^{-2}} \right)^{-3} =\left(\dfrac{m^{-1+5}}{m^{-2}}\right)^{-3}$

$\sf = \left(\dfrac{m^4}{m^{-2}}\right)^{-3}\\\\$

$\boxed{\dfrac{a^{m}}{a^{n}}=a^{m+n}}$

$\sf = \left(m^{4-[-2]}\right)^{-3}\\\\ =\left(m^{4+2}\right)^{-3}\\\\ = \left(m^6\right)^{-3}\\\\$

$\boxed{(a^{m})^n=a^{m*n}}$

$\sf= m^{6*(-3)}\\\\ = m^{-18}$

$\boxed{a^{-m}=\dfrac{1}{a^m}}$

$\sf=\dfrac{1}{m^{18}}$
