How do you write #4a^0*7a^-4# using only positive exponents?

Answer 1

See a solution process below:

First, simplify the term on the left using this exponents rule:

#a^color(red)(0) = 1#
#4a^color(red)(0) * 7a^-4 =>#
#(4 * 1) * 7a^-4 =>#
#4 * 7a^-4 =>#
#28a^-4#

Apply the following exponent rule to get rid of the negative exponent:

#x^color(red)(a) = 1/x^color(red)(-a)#
#28a^color(red)(-4) =>#
#28/a^color(red)(- -4) =>#
#28/a^color(red)(4)#

4a^0 * 7a^-4 can be written using only positive exponents as ( \frac{4 * 1}{7a^4} ) or simply ( \frac{4}{7a^4} ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
