Question

What value of x makes this equation true?

Answer 1

The process of finding out the variable value that makes the equation true is called 'solving' the equation. An equation is a statement that two quantities are equivalent. For exp/example:. x + 1 = 4 mean that when we add 1 to the unknown value, 'x', the answer is equal to 4 .

Answer 2

Value of x makes this equation true = -3

Further explanation

In general, we are dealing with numbers that can have large or small numbers

This rank number was originally used as a multiple product

Rank numbers are usually used in scientific notation. Scientific notation is used to express very large / small numbers

Rank notation is used to write the product of repeated numbers in a simple form.

Rank form functions is to simplify writing and mention of a number that has the same multiplication factors

Rank Number Operations

• 1. multiplication
• 2. division
• 3. addition
• 4. substraction

Rank numbers can be

• 1. positive integers
• 2. zero integers
• 3. negative integers

General properties of numbers:

• 1. aᵇ x aⁿ = aᵇ⁺ⁿ

• 2. aᵇ: aⁿ = aᵇ⁻ⁿ, a ≠ 0

• 3. a⁻ᵇ = 1 / aᵇ, a ≠ 0

• 4. (aᵇ) ⁿ = aᵇⁿ

aⁿ: rank number

If we look the task:

The equation:

$5^{-2x-10}=25^{x+1}$

We change to

$5^{-2x-10}=5^{2(x+1)}$

Then

-2x-10 = 2(x+1)

-2x-10 = 2x+2

-4x = 12

x = -3
