write the product of the expression 5^4 * 5^-7 using a positive exponent, then write the product using a negative exponent

pav-90 [236]

Answer with positive exponent = $\left(\frac{1}{5}\right)^3$ or $\frac{1}{5^3}$

Answer with negative exponent = $5^{-3}$

===========================================================

Explanation:

The rule we use is

$a^b*a^c = a^{b+c}$

If we multiply two exponential expressions with the same base, then we add the exponents.

The base for each is 5. The exponents 4 and -7 add to -3.

This means

$5^4*5^{-7} = 5^{4+(-7)} = 5^{-3}$

To convert to a positive exponent, we apply the reciprocal to the base. We go from 5, aka 5/1, to 1/5.

So, $5^{-3} = \left(\frac{1}{5}\right)^3 = \frac{1^3}{5^3} = \frac{1}{5^3}$

A baker bakes a batch of muffins and splits the batch evenly onto six different trays. She then adds five croissants to each tra

Eduardwww [97]

Answer:

Step-by-step explanation:

Using inequalities we can understand this problem.

First call X the number of products in the original batch

Then X/6 is the number of muffins in each tray before putting the croissants

Finally, X/6+5 are the products in each tray counting the croissants, and this quantity at least should be 20, it means:

$\frac{X}{6}+5\geq 20$

Isolating X:

$\frac{X}{6}\geq 20-5\\\frac{X}{6}\geq 15\\X\geq 6*15\\X\geq 90$

The least possible number of muffins in the baker's original batch is 90.
