What is 25.5n - 3 = 5.5n + 10.
klemol [59]
N = 13/20 or 0.65

25.5n - 3 = 5.5n + 10

Add 3 to both sides of the equation.

25.5n = 5.5n + 13

Subtract 5.5n from both sides.

20n = 13

Divide both sides by 20.

n = 13/20 or 0.65

What is the monomial if a square of a monomial is:1 9/16 a12b6
san4es73 [151]

Answer:

1\dfrac{1}{4}a^6b^3

Step-by-step explanation:

A square of a monomial is 1\dfrac{9}{16}a^{12}b^6 that is \dfrac{25}{16}a^{12}b^{6}

Use properties of exponents:

(a^m)^n=a^{mn}\\ \\\dfrac{a^m}{b^m}=\left(\dfrac{a}{b}\right)^m\\ \\a^mb^m=(ab)^m

Note that

\dfrac{25}{16}=\dfrac{5^2}{4^2}=\left(\dfrac{5}{4}\right)^2\\ \\a^{12}=a^{6\cdot 2}=(a^6)^2\\ \\b^6=b^{3\cdot 2}=(b^3)^2

Then

\dfrac{25}{16}a^{12}b^{6}=\left(\dfrac{5}{4}\right)^2\cdot (a^6)^2\cdot (b^{3})^2=\left(\dfrac{5}{4}a^6b^3\right)^2

So, the monomial is

\dfrac{5}{4}a^6b^3=1\dfrac{1}{4}a^6b^3
