Tell how you can determine whether a number is a solution of an equation. TE; ME YOUR OWN ANSWER FOOL

Substitute the number for the variable in the condition. Rearrange the articulations on the two sides of the condition. In the event that it is valid, the number is an answer. On the off chance that it isn't correct, the number isn't an answer.

Step-by-step explanation:

In my own words, put it in a plagiarism checker :D

step-by-step explanation:

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.
