Logarithms are studied for which of the following​ reasons? A. To help in solving exponential equations when relating the bases
skad [1K]

Answer:

To help in solving exponential equations when relating the bases cannot be used

Step-by-step explanation:

Recall an equation of the form

a^{x}=b\\ from the expression a^{x}\\, a\\ is the base and the power is {x}\\.

a\neq b\\ it is impossible to carryout the operation since the bases are not equal.

This is where we implore the help of logarithm which help us to bring the base to a come base i.e using the property below

loga^{x}=logb\\x=\frac{logb}{loga} \\.

Hence we can conclude that logarithm helps in solving equations when bases cannot easily be related.

jeka94

Answer:

a. 20x > 10x + 80

b.  •20x > 10x + 80

• Subtract 10x from both sides: 20x -10x > 10x + 80 - 10x

• Simplify: 10x > 80

• Divide both sides by 10:   10x/10 > 80/10

• Simplify: x > 8

Step-by-step explanation:

10x + 80 = number of seashells Pilar has.

20x = number of seashells Marisol has.  

answer for a:  20x > 10x + 80

answer for b: 20x > 10x + 80

• Subtract 10x from both sides: 20x -10x > 10x + 80 - 10x

• Simplify: 10x > 80

• Divide both sides by 10:   10x/10 > 80/10

• Simplify: x > 8
