In this situation, 6 is an even exponent which means that the negative coefficient of this 9th degree monomial will be positive. Now the only step is to multiply the exponents by the exponent outside of the perenthesis which is 6.
so (-a³b⁴c⁹)⁶ = ((-a³)⁶(b⁴)⁶(c⁹)⁶) = ((a³ˣ⁶)(b⁴ˣ⁶)(c⁹ˣ⁶)) = ((a¹⁸)(b²⁴)(c⁵⁴)) = a¹⁸b²⁴c⁵⁴

how does simple
interest show proportional reasoning and
relate to the percent equation?
Answer:
Use cross product to determine if the two ratios form a proportion. Here we can see that 2/16 and 5/40 are proportions since their cross products are equal. Percent means hundredths or per hundred and is written with the symbol, %. Percent is a ratio were we compare numbers to 100 which means that 1% is 1/100.
Step-by-step explanation:
Simple interest show proportional reasoning and relate to the percentage equation.
Relationship between percentage and proportion:The relationship between proportion and percentage occurs when a particular proportion gets multiplied by 100 it gives the percentage of parts takenmeans,
[tex]\dfrac{\text{Parts}}{Whole}\times 100= \text{Percentage}[/tex]
Similarly,
when a percent gets multiplied by total it gives the number of parts taken means,
[tex]\text{Parts} = \text{percent} \times\text{whole}[/tex]
We can also use cross product to find out if the two ratios form a proportion.Here we can see that 3/15 and 6/44 are proportions, since their cross products are equal.
Percent means hundredths or per hundred and is written with the signal, %. Percent is a ratio where we compare numbers to 100 which means that 1% is 1/100.
Therefore, simple interest show proportional reasoning and relates to the percentage equation.
