Which expression is equivalent to (5^-2)(5^-1)
nadya68 [22]
The rule for multiplying similar bases with exponents:

(a^b)(a^c)=a^(b+c)

In this case we have:

(5^-2)(5^-1)

5^(-2-1)

5^(-3)

The rule for negative exponents:

a^(-b)=1/(a^b)

So in this case:

5^(-3) is equal to 

1/(5^3)

1/125

What is n-9 divided by 10=-2
DerKrebs [107]

The value of n is 11.

<u>Step-by-step explanation</u>:

The given expression is (n-9) ÷ 10 = -2

<u>To find the value of n</u> :

  • From the expression, it is determined that (n-9) is the numerator and 10 is the denominator.
  • Cross multiply the denominator in the left side of the expression to the another side.

The expression becomes (n-9) = (10\times -2).

⇒ n-9 = -20

Keep the n term on one side and the constants on other side.

⇒ n = -20+9

⇒ n = -11

Therefore, the value of n is 11.

Plz help me answer right away ASAP!!!
Illusion [34]

First you take 15 and divide it by 5. That leaves you with 3. You also need to decide the x’s so you subtract the exponents (2-3=-1)

so you now have (y^10z^7)/(y^4z^10)3x^-1

Next we will divide the y’s.

Again, subtract the exponents (10-4=6) to get y^6

Now we have (3x^-1)(y^6) (z^7/z^10)

Last is z, we subtract the exponents again (7-10=-3) and get z^-3

Our answer is (3x^-1)(y^6)(z^-3)
