Simplify completely the radical expression sqrt(735) Write your answer as a number a*sqrt(b).

What is the sum of a and b?

Simplifying the radical expression we get  

Write your answer as a number a*sqrt(b)

What is the sum of a and b?

We can't find the sum of a and b.

Step-by-step explanation:

We need to simplify completely the radical expression

First we need to find prime factors of 735

Prime factors of 735 are: 3x5x7x7

Solving:

So, simplifying the radical expression we get  

Write your answer as a number a*sqrt(b)

What is the sum of a and b?

We can't find the sum of a and b.

where is the rest of the

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.
