Evaluate the expression 6 squared parentheses 2/5 + 5 parentheses -3

To start off you do what’s in parentheses

2/5 + 5 = 5 2/5 or 5.4 as a decimal

Then the exponent 6^2 which is 36

So far you have 36 (5.4) - 3

Now you multiply 36 by 5.4 which is 194.4

So now you have 194.4 - 3 which equals 191.4 which is you answer.

Hope this helped!

answer: 1 + 1 = 11

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.
