find the root of this problem -1 + 6/ 2. but under the plus sign there is a line. idk how to put the symbol

Step-by-step explanation:

Step 1: Divide 6 by 2.

Step 2: Add -1 and 3.

Step 3: Subtract 3 from -1.

Step 4: The complete solution is the result of both the positive and negative portions of the solution.

step-by-step explanation:

goog be able to you with that maybe

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
