Answer:

\frac{81}{m^7}

Step-by-step explanation:

We have a certain expression and are asked to find its equivalent with the answers provided :

(3m^{-4} )^3(3m^5)

Remove the parenthesis around 3m^5 :

(3m^{-4} )^3*3m^5

Do the exponent rule for outside and inside exponent parenthesis :

(3m^{-4*3} )

3^3m^{-12} *3m^5

Apply addition exponent rule :

m^{-12} *3^{3+1} m^5

Add :

m^{-12} *3^4m^5

Apply the addition rule for -12 + 5 :

3^{4} m^{-7}

Apply negative exponent rule for m^-7 :

3^4*\frac{1}{m^7}

Multiply the fractions :

\frac{1*3^4}{m^7}

\frac{81}{m^7}

3hrs= 60x3=180mins

1hr= 60x1=60mins

then you add 20 to 180
