53,806 in expanded form using exponents

5×10⁴ + 3×10³ + 8×10² + 6×10⁰

Explanation:

1) The expanded form of a number is the same number written as the sum of each digit according to its place value.

Using exponents, powers of ten, is very simple as each power is the number of the place value.

This table will help you:

Place value power of ten

hundred thousands - 100,000 10⁵

ten thousands - 10,000 10⁴

thousands - 1,000 10³

hundreds - 100 10²

tens - 10 10¹

ones - 1 10⁰

2) Now, I will show you how to do it with your number: 53,806.

i) The digit 5 is in the ten thousands place, the 3 is in the thousands place, the 8 is in the hundreds place, the 0 is in the tens place, and the 6 is in the ones place.

ii) So:

5 represents 50,000, or 5×10⁴;

3 represents 3,000, or 3×10³;

8 represents 800, or 8×10²; and

6 represents 6, or 6×10⁰.

iii) Then, the expanded form is the representation of the number as the sum of those values, which is:

5×10⁴ + 3×10³ + 8×10² + 6×10⁰.

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
