HELP PLS I GIVE BRAINLIST part 1. create 2 radical equations one that has an extraneous solution, and one that does not have an extraneous solution. use the equation below as a model. use a constant in place of each variable a, b,c, and d. you can use positive and negative constants in your equation.
a√(x+b) + c=d that has an extraneous solution
a√(x+b) + c=d that does not have an extraneous solution
part 2. show your work in solving the equation. include the work to check your solution and show that your solution is extraneous.
a√(x+b) + c=d that has an extraneous solution
a√(x+b) + c=d that does not have an extraneous solution
part 3. explain why the first equation has an extraneous solution and the second does not
PLS ANSWER ASAP THANKS

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.

333.74 ! should be your answer for this question

a. true

if you are using power tools in or around standing water, you should continue and always proceed with caution.
