–4g + 5h = 4 8g + 10h = –4

1 answer:

7 0

Multiply the 1st equation by 2: ====> -8g +10 h = 8, then add it to the 2nd equation [( -8g+10h=8) + (8g+10h = -4) ] & you will get h=4/20 = 1/5.

Plug this value to find g

What is the simplified form of StartFractio negative 24 m Superscript 5 Baseline n Superscript 4 Baseline Over 8 m Superscript n

Aleks04 [339]

Answer:

$\frac{-24m^5n^4}{8m^{-7}n^{-2}}=-3m^{12}n^{6}$

Step-by-step explanation:

Given:

The expression to simplify is given as:

$\frac{-24m^5n^4}{8m^{-7}n^{-2}}$

We have to simplify this using the properties of exponents.

The property that we use here is:

$\frac{a^m}{a^n}=a^{m-n}$

So, let us simplify the powers of $m\ and\ n$ separately and -24 and 8. This gives,

$\frac{m^5}{m^{-7}}=m^{5-(-7)}=m^{5+7}=m^{12}\\\frac{n^4}{n^{-2}}=n^{4-(-2)}=n^{4+2}=n^6\\\frac{-24}{8}=-3$

Therefore, the simplified form is:

$\frac{-24m^5n^4}{8m^{-7}n^{-2}}=-3m^{12}n^{6}$
