To do this without a calculator, I would change:  5.2 × 10^(-2) to ... 52×10^(-3)

--> then multiply the whole numbers 52 × 8 = 416

--> next add the exponents on the tens. -3 + -4 = -7

= 416×10^(-7)

* now they'll want you to move the decimal back to behind the first digit. (just standard convention)

= 4.16×10^(-5)

If you have a calculator you can just use the "EE" button for ×10^power typed in it looks like this :

5.2 EE -2 × 8 EE -4 =

then make sure your calculator is in scientific mode, otherwise you'll be counting decimal spaces

Solve 6 2/3 -1 1/2+4 1/6​
Tju [1.3M]

Answer:

9 1/3

Step-by-step explanation:

Make 2/3 , 1/2 , & 1/6 have the same denominator. 6 is the least common multiple for all 3 fractions.

2/3 gets multiplied by 2/2

1/2 gets multiplied by 3/3

1/6 stays the same

2/3 becomes 4/6

1/2 becomes 3/6

1/6 stays 1/6

Follow the order of operations from the original equation.

4/6 - 3/6 = 1/6 then 1/6 + 1/6 = 2/6

6 - 1 = 5 then 5 + 4 = 9

Simplify 2/6 to 1/3

Remember to add 1/3 back to 9 making it 9 1/3
