how to slove this more complex negative exponent problem?
When an expression or a number is raised to the negative exponent, you have to reciprocate the expression or the number.
In this problem, the expression is raised to the power of -2
Therefore, the expression would become like this after reciprocating:
1/ (3x^2) ^2
Simplifying the expression:
1/ 9x^4
Is it necessary to use the formulas for special products of binomials to multiply these binomials?
Final answer:
While it's not necessary to use the binomial theorem to multiply binomials, it can greatly simplify the process. This theorem is handy for higher powers and in cases where technology tools are not available.
Explanation:
The formulas for special products, like the binomial theorem, are not always necessary for multiplying binomials, but they can simplify the process significantly, especially for higher powers. When multiplying binomials without these formulas, one would have to apply the distributive property multiple times, which can be tedious and prone to error. The binomial theorem provides a direct way to expand binomials raised to a power in a series expansion: (a + b)n = an + n*an-1*b + ... + bn. Utilizing this formula can speed up calculations and help avoid mistakes.
In understanding series expansions, working with exponents, and creating formulas based on logical sense and unit consistency, students can sometimes simplify problems without needing to memorize formulas. However, for complex problems or when working with large exponents, knowing and applying the binomial theorem can be much more efficient.
Moreover, technologies like calculators and computer software often have functions that apply these theorems or carry out the multiplications of binomials, which can make manual calculations unnecessary, provided you have access to these tools. But understanding the underlying principles is important for a strong mathematical foundation.

a car is travelling at x kilometres per hour find the cars speed, in terms of x in metres per second give your answer in its simplest form
To convert a car's speed from kilometers per hour (x km/h) to meters per second, divide x by 3.6. This is because there are 1,000 meters in a kilometer and 3,600 seconds in an hour, leading to the simple formula: x / 3.6 m/s.
Explanation:To find the car's speed in meters per second (m/s) when it is traveling at x kilometers per hour (km/h), we need to convert km/h to m/s. There are 1,000 meters in a kilometer and 3,600 seconds in an hour. So, to convert from km/h to m/s, we use the conversion factor 1 km = 1,000 m and 1 hour = 3,600 seconds.
The formula to convert x km/h to m/s is: x \(\times\) 1,000 m / 3,600 s. Simplifying this, we get:
x \(\times\) 1,000 / 3,600 = x / 3.6 m/s.
Therefore, if a car is traveling at x kilometers per hour, its speed in meters per second is x / 3.6 m/s in its simplest form.

Emma created the poster shown below: A rectangle is shown. The length of the rectangle is labeled as length equal to 36 cm, and the width is labeled as width equal to 24 cm. What would be the dimensions of the poster at fraction 1 over 4 times its current size? Length = 32 cm, width = 20 cm Length = 40 cm, width = 28 cm Length = 144 cm, width = 96 cm Length = 9 cm, width = 6 cm
Answer:
Length = 9 cm, width = 6 cm
Step-by-step explanation:
If the length of the rectangle is labeled as length equal to 36 cm, and the width is labeled as width equal to 24 cm.
Length = 36cm
Width = 24cm
One fourth the current size of the rectangle will be;
New length= 1/4×36 = 9cm
New width = 1/4 × 24 = 6cm
The new dimension of the poster is therefore 9cm×6cm
Length = 9cm
Width = 6cm

Evaluate the expression when a=−15 and b=−5.
b2
------------ =
a + 5
Help
The value of the given mathematical expression b^2 divided by a+5 when a=-15 and b=-5 is -2.5.
Explanation:In the given expression, we're asked to evaluate b2 divided by (a + 5), where a = -15 and b = -5. First we substitute the values of a and b into the expression.
So, b2 becomes (-5)2 = 25 and a + 5 becomes -15 + 5 = -10.
Now, substituting these results back into the original expression, we get 25 divided by -10, which equals -2.5.
Therefore, the value of the given expression when a=-15 and b=-5, is -2.5.
