a .75 \% \\  \\ a.400 \\  \\ b.no

Step-by-step explanation:

1...... \: let \: the \: percentage \: be \: x \% \\ then \: x \% \: of \: 500 = 375 \\  (\frac{x}{100} )500 = 375 \\ 5x = 375 \\ x =  \frac{375}{5}  \\ \boxed{ x = 75\%} \\  \\ 2.....80\% \: of \: 500 = ( \frac{80}{100} )500 \\ 80\% \: of \: 500 = 80 \times 5 \\ \boxed{ 80\% \: of \: 500 = 40 0}\\  \\ 3.....60\% \: of \: 200 = ( \frac{60}{100} )200 \\ 60\% \: of \: 200 = 60 \times 2\\ \boxed{ 60\% \: of \: 200 = 120} \\ ........his \: statement \: was \: reasonable \: wrong

Simplify 4 to the 7th over 5 squared all raised to the 3rd power.
Radda [10]
First write out your original equation.
{(\frac{ {4}^{7} }{ {5}^{2} } ) }^{3}
Then use the law of exponents(power of a power) to simplify.
\frac{ {4}^{21} }{ {5}^{6} }
(Multiply the numerator and denominator exponents by the outside power.)

The answer is 4 to the 21st over 5 to the 6th.
