Enter the correct answer in the box. What is this expression in simplified form?
3\sqrt{88}

Step-by-step explanation:

88 can be rewritten as 8 x 10 and 8 can be rewritten as making a 2 come out of the root.

10 can be rewritten as 2 x 5.

2*2 can also be rewritten as making a 2 come out of the root.

We can't keep simplifying the root.

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.
