Which rules of exponents will be used to evaluate the expression. check all that apply [(7^5)(7^3)]^-4

quotient of powers
product of powers
power of a power
power of a product
negative exponent
zero exponent

plz help

Step-by-step explanation:

The value in square brackets is evaluated using the product of powers rule:

  (7^5)(7^3) = 7^(5+3) = 7^8

Then the overall value is found using the power of a power rule:

  [7^8]^-4 = 7^(8(-4)) = 7^-32

Finally, the expression value is found using the negative exponent rule:

  7^(-32) = 1/7^32 = 1/1104427674243920646305299201

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
