Answer 1

Remember the rule of Exponential division?

When an exponent is divided by another exponent, the exponent in the numerator is subtracted by the exponent in the denominator

So in this case you’re looking at
\(\sf{\dfrac{4}{5} \times 10^{7-8}}\)

Once you get that you have -1, which when you do \(\sf{\dfrac{4}{5}}\) — gives you 0.8. Then using the rule of negative exponents to fractions, you can make 0.8 into 8 and \(\sf{10^{-1}}\) into \(\sf{10^0}\) (because a negative exponent is the same as changing the decimal to the right one place.



Best of luck,
