Explanation:

Multiply each term within the parenthesis by the term outside the parenthesis. Use these rules for exponents:

$a={a}^{1}$ and $x}^{a}\times {x}^{b}={x}^{a+b$

$5mn(7m-2n)\Rightarrow$

$(5mn\times 7m)-(5mn\times 2n)\Rightarrow$

$(5{m}^{1}n\times 7{m}^{1})-(5m{n}^{1}\times 2{n}^{1})\Rightarrow$

$35{m}^{1+1}n-10m{n}^{1+1}\Rightarrow$

$35{m}^{2}n-10m{n}^{2}$

Multiply each term within the parenthesis by the term outside the parenthesis. Use these rules for exponents:

$\frac{20b}{{\left(4{b}^{3}\right)}^{3}}$
