Express each logarithm in terms of In 2 and In 5.
Sladkaya [172]

Answer:

5ln2-3ln5

2ln5-ln2

Step-by-step explanation:

∵ 32=2^{5}

∵ 125=5^{3}

∵ ln\frac{32}{125}=ln\frac{2^{5}}{5^{3}}

∴ ln2^{5}-ln5^{3}=5ln2-3ln5

∵ 12.5=\frac{125}{10}=\frac{25}{2}=\frac{5^{2}}{2}

∴ ln12.5=ln\frac{5^{2}}{2}

∴ ln5^{2}-ln2=2ln5-ln2

Prove that for a triple element x, y, z the distributive law is always satisfied if one of the elements equals 0 or 1, or if two
solmaris [256]

The distributive law is satisfied if the numbers 1,2, and 3 are used as multyplying factors.

<h3>What is the distributive law?</h3>

This is basic mathematical law that states:

  • A multiplied by (b+c) equals (a x b) + (a x c)

<h3>Is this law satisfied if there are three numbers involved?</h3>

The law is always satisfied if one of the numbers is 1. Here is an example

  • 2 x (1+2+3) = 2 x 6 = 12

or

  • (2x1) + (2x2) + (2x3)
  • 2+4+6 = 12

Rom4ik [11]

Answer:

8

Step-by-step explanation:

We are required to evaluate:

0.1m+8-12n

When m=30, n=\frac{1}{4}

Substituting these values into the expression, we have:

0.1m+8-12n=0.1(30)+8-12(\frac{1}{4})\\=3+8-\frac{12}{4}\\=3+8-3\\=8
