Answer:

16. D

17. 5^-1 · 5^-1 and 25^-1

8^0 · 8^3 and 8^3

Step-by-step explanation:

When you multiply two same numbers with exponents, just think of it as adding up exponents.

When you divide two same numbers with exponents, just think of it as subtracting exponents.

If a parenthesis has an exponent outside, then every exponent inside the parenthesis will be multiplied by that outside parenthesis.

(5^-1)^-2 · 5^3 ÷ 5^7

5^2 · 5^3 ÷ 5^7

5^5 ÷ 5^7

5^-2

When exponents are negative, you have to flip them or put them on the other side

5^-2 = 1/5^2 = 1/25

Let's try to find the equivalent pairs

6^7 ÷ 6^-2 = 6^5

6^9 = 6^5 Not equivalent

(6^3)^0 = 6

6^0 = 1 (Any number with a zero exponent is always 1)

1 = 6 Not equivalent

5^-1 · 5^-1 = 25^-1

5^-2 = 25^-1

Flip em

1/5^2 = 1/25

1/25 = 1/25 Equivalent

8^0 · 8^3 = 8^3

8^3 = 8^3 Equivalent

4^-3 ÷ 4^2 = 4^5

4^-5 = 4^5 Not equivalent

Answer:

Hey there!

Perimeter: 24

Area: 24

36+64=x^2

x=10

Perimeter: 10+6+8=24

Area: 1/2bh, 1/2(48)=24

Both the area and perimeter are 24.

Hope this helps :)

What is the difference between decimal and binary numbering systems give examples of when you would use each?
vaieri [72.5K]

The difference between decimal and binary system are-

  • The base-10 system, often known as the decimal system, is the oldest and most widely used system of numbers.
  • The binary number system, often known as base 2, is used by computers.
<h3>What is decimal system?</h3>

Our daily use of numbers is based on a decimal number system, which uses 10 digits. A number system in mathematics is thought of as the use of digits or symbols to represent numbers.

  • The binary number system, the decimal number system, the octal number system, and the hexadecimal number system are the four primary varieties of the number system.
  • Given that it was challenging to multiply & divide big numbers by hand in earlier civilizations, this decimal system system is sometimes called as the Hindu-Arabic and Arabic number system.
<h3>What is binary system?</h3>

The base-2 number system is the binary system. That implies that it solely use the digits 0 and 1. The 1 one location is moved to its left into the 2s place when adding one to one, and a 0 is placed in the ones place, yielding the number 10. In such a base-10 system, 10 thus = 10. 10 = 2 in the base-2 system.

  • The place values in a base-2 system begin with ones and progress to twos, fours, then eights as one move to its left.
  • This is due to the base-2 system's foundation in powers of two.
  • A bit is the term for each binary digit.

Therefore, a binary number system only employs two different digits(0 and 1), whereas decimal number system includes ten different digits (ranging from 0 to 9).
