Applying the rules of exponents, the letter answers that form the code are: MATH IS NOT JUST ANOTHER FOUR LETTER WORD.

<h3>What are the Rules of Exponents?</h3>

Some of the rules of exponents to be applied are as follows:

x^0 = 1\\\\x^m \times x^n = x^{(m + n)}\\\\x^{-m} = \frac{1}{x^m} \\\\x^m \div x^n = x^{(m - n)}\\\\

<h3>What are Equivalent Expressions?</h3>

If two expressions have the same value, both are said to be equivalent expressions.

1. 3^2 \times 3^{-5} = 3^{2 - 5}\\\\

3^-3 = \frac{1}{3^3} = \frac{1}{27}

Answer: H

2. 3³/6² = 27/36 = 3/4

Answer: R

3. \frac{3^2}{3^5} = 3^{2 - 5} = 3^{-3]} = \frac{1}{3^3} = \frac{1}{27}

Answer: M

4. 7²/7² = 49/49 = 7° = 1

Answer: J

5. 8^-2 = 1/8² = 1/64

Answer: A

6. (4²)(4³) = 4^(2 + 3) = 4^5

Answer: L

7. (3²)³ = 3²*³ = 3^6

8. 4° × 4^-1 = 1 × 1/4 = 1/4

Answer: E

9. \frac{(2^4)^3}{(2^7)(2^5)} = \frac{2^{12}}{2^{12}} = 1

Answer: U

10. (3^2)^{-1} = 3^{-2}

Answer: I

11. 1^{98} = 1

Answer: D

12. y^{10} \div y^5 = y^{10 - 5} = y^5

Answer: F

13. 8^{-2} \times 8^4 = 8^{(-2 + 4)} = 8² = 64

Answer: S

14. 2^{-3} \times 3^{-2} = 1/2³ × 1/3² = 1/8 × 1/9 = 1/72

Answer: O

15. \frac{3^2}{3^2} = 3^{2-2} = 3^0 = 1

Answer: N

16. (\frac{1}{2} )^{-1} = (2^{-1})^{-1} = 2

Answer: T

Thus, applying the rules of exponents, the letter answers that form the code are: MATH IS NOT JUST ANOTHER FOUR LETTER WORD.

Can someone please help!!!!!
Artist 52 [7]

Answer:

The answer is 10%

Step-by-step explanation:

Let the length of the rectangle is x

Let the width of the rectangle is y

∵ They will increase by 10% each

∴ The new length = x × 110/100 = 1.1x

∴ The new width = y × 110/100 = 1.1y

∵ The old perimeter = 2(x + y) = (2x + 2y)

∴ The new perimeter = 2(1.1x + 1.1y) = 1.1(2x +2y)

∴ The new perimeter is greater than the old perimeter by 1.1 - 1 = 0.1

∴ The percentage of increasing in the perimeter = 0.1 × 100 = 10%

How do i solve for A=1/2πr2 (for π)
astraxan [27]

Answer:

2A/r^2 = pi

Step-by-step explanation:

A=1/2πr^2

multiply each side by2

2A = 2*1/2 pi r^2

2A = pi*r^2

divide each side by r^2

2A/r^2 = pi r^2/r^2

2A/r^2 = pi
