Answer:

base: 4

exponent: 3

numerator: 1

denominator: 64

Step-by-step explanation:

4^4 * 4^-2: Here you subtract 2 from 4 (just basic rules)

so you get 4^2/4^5

4^2/4^5: you subtract 5 from 2 (also basic rules)

then you would get 4^-3

To put in positive exponents you do 1/4^3

which gets you 1/64

Please help. 10 points and brainliest.
Snezhnost [94]

Answer:

\frac{a^2}{b^2}

Step-by-step explanation:

Apply the exponent rule a^b*a^c=a^b+c to a

a^4*a^-^2=a^4^-^2=a^2

b^3a^2b^-^5

Apply the exponent rule to b

b^3*b^-^5=b^3^-^5=b^-^2

Apply the exponent rule a^-^b=\frac{1}{a^b}

b^-^2=\frac{1}{b^2}=\frac{1}{b^2}a^2=\frac{a^2}{b^2}

Why does the multiplicative inverse of a number have the same sign as the number?
denis23 [38]
<span>Look at the definition of multiplicative inverse. If two numbers are multiplicative inverses of each other, then by definition, their product will be equal to 1. And 1 is a positive number. If both numbers being multiplied are positive, then the result is positive. And of both numbers being multiplied are negative, then the result is still positive. But if one number is positive and the other is negative, then the result is negative. So if you want a positive result, then both numbers you're multiplying have to have the same sign. And since we want a result of 1 for multiplicative inverses and since 1 is positive, then the numbers being multiplied have to have the same sign.</span>

Ann Zoe and Jim bought a present for ben. Ann cooperated with $12 less than Zoe and $16 less than Jim. If the cost of the presen
sergeinik [125]

Let A represent the amount Ann contributed, Z represent Zoe's contribution, and J represent Jim's contribution toward the present.

Ann (A): A

Zoe (Z): A = Z - 12 → Z = 12 + A

Jim (J): A = J - 16 → J = 16 + A

A + Z + J = 154

(A) + (12 + A) + (16 + A) = 154

3A + 28 = 154

3A = 126

A = 42

Ann (A): A = 42

Zoe (Z): Z = 12 + A = 12 + 42 = 54

Jim (J): J = 16 + A = 16 + 42 = 58

Answer: Ann=42, Zoe=54, Jim=58

Step-by-step explanation:

The property is actually a property <em>of the set of polynomials</em>, rather than a property of <em>multiplication</em>.

The set of polynomials is closed under the operation of multiplication. We call that property <em>closure</em>.
