Answer:

$y^6$

Step-by-step explanation:

$\frac{a^b}{a^c} = a^{b - c}$

Using this rule we have:

$\frac{y^{-7}}{y^{-13}} = y^{-7 -(-13)} = y^6$

Answer:

$y^6$

Step-by-step explanation:

The applicable rules of exponents are ...

$y^ay^b=y^{a+b}\\\\\dfrac{1}{y^{-a}}=y^a$

Using these rules, you can write the expression as ...

$\dfrac{y^{-7}}{y^{-13}}=y^{-7-(-13)}=y^6$

Rewrite the following equation in log form: 2^2 = 4

Finger [1]

We have to write

$2^2 =4$

In log form

To convert exponential equation to log equation, we have to use the following rule $If \ a^b = c, \ then \ b=log_{a} c$

So we will get

$If \ 2^2 =4, \ then \ 2 = log_{2} 4$

$log_{2}4=2$

And that's the required log form .

Given that 35.8 x 4.23= 151.434<br>write down a division sum with an answer of 423.

Nina [5.8K]

Answer:

151434/358 = 423

Step-by-step explanation:

Every product with non-zero factors can be written as an equivalent division relation.

a·b = c ⇒ a = c/b

Here, we have 35.8 × 4.23 = 151.434. This can be written as the equivalent ...

4.23 = 151.434/35.8

We can multiply this by 100 to get a division relation with a quotient of 423:

423 = 15143.4/35.8

If we want, we can move the decimal points another place to the right to get ...

151434/358 = 423

If MN = x+4 and DE = 3x-2, find x. (More info in pic)

algol [13]

Answer: D) 10

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

Explanation:

I'm assuming points M and N are midpoints of segments FD and FE respectively. If that's the case, then segment DE is twice as long compared to segment MN. We consider MN to be a midsegment.

So,

DE = 2*(MN)

3x-2 = 2*(x+4)

3x-2 = 2x+8

3x-2x = 8+2

x = 10
