Simplify this expression.
Bond [772]

The correct expression to simplify is:

1+4.25n + 3/2p -3+(-2p)+5/4n

Answer:

5.5n-1/2p-2

Explanation:

<u>1. Given expression</u>:

1+4.25n + 3/2p -3+(-2p)+5/4n

<u>2. Group like terms</u>:

(1-3)+(4.25n+5/4n)+(3/2p-2p)

<u>3. Simplify</u>:

  • 1 - 3 = - 2
  • 4.25n + 5/4n = 4.25n + 1.25n = 5.5n
  • 3/2p - 2p = 1.5p - 2p = - 0.5p = - 1/2p

-2+5.5n-1/2p=5.5n-1/2p-2

Describe the similarities and differences in solving the equations 4^5x-1=16 and log4(10x+2)=1 Then solve each question
Brilliant_brown [7]

Answer:

4^5x-1=16

4^5x-1=4²eliminate 4

5x-1=2

5x=2+1

5x=3

x=3/5

log4(10x+2)=1

log4(10x+2)=log4 ⁴

eliminate log4

10x+2=4

10x=4-2

10x=2

x=2/10

x=1/5

difference between the is we use law of indices and logarithm to the questions respectively

similarities is we eliminate there base
