Answer:

n = 1, 4

Step-by-step explanation:

Step 1: Write equation

n² - 5n + 4 = 0

Step 2: Solve for <em>n</em>

<u>Factor:</u> (n - 4)(n - 1) = 0

<u>Find roots:</u> n = 1, 4

Step 3: Check

<em>Plug in n to verify if it's a solution.</em>

1² - 5(1) + 4 = 0

1 - 5 + 4 = 0

-4 + 4 = 0

0 = 0

4² - 5(4) + 4 = 0

16 - 20 + 4 = 0

-4 + 4 = 0

0 = 0

If you solve by factoring this would be the process of it
Step 1: Factor left side of the the equation
(n-1)(n-4)=0
Step 2: set factors equal 0
n-1=0 or n-4=0
then you would solve both like a regular equation
n=1 or n=4 would be the answers

The mass of a proton is about 1.7 \times 10^(-24). Write this number in standard notation.
OLga [1]

Now we have a negative exponent, which is the opposite of a positive exponent.

If a positive exponent means you're multiplying by 10s and it makes a number bigger by moving the decimal to the right, then

the opposite of this is that a negative exponent means you're dividing by 10s and making the number smaller by moving the decimal point to the left.

 

Examples:

930 \div 10 = 93

{\bf930 \div 10} \div 10 = {\bf 93} \div 10 = 9.3

 

The trick is to recognize that

930 \div 10 is the same thing as 930 \times 10^{-1}

{}\div 10 and {}\times 10^{-1} mean the same thing.

So, 930 {\bf {}\div 10 \div 10} = 930 {\bf {}\times 10^{-1}  \times 10^{-1}} = 930 {\bf {}\times 10^{-2}} = 9.3

 

For your exercise, {}\times10^{-24} means you'll move the decimal point 24 places to the left, to make the number smaller.
