1.5 × 10'3
1.05 × 10'5
1.5 × 10'4
1.05 × 10'3

.

Step-by-step explanation:

Given  : 105,000

To find : Rewrite 105,000 in scientific notation.

Solution : We have given  105,000 .

Steps to write in scientific notation :

Step 1 : If a number has n digit we move decimal point ( n-1) place to left  and to balance , multiply by .

We can see there are n = 6 in 105,000

So, we move decimal point 5 place to the left .  

Then  .

Therefore,  .

answer: are you

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
