Which of these expressions is equivalent to 2f x 2f x 2f x 2f x 2f x 2f

Option choice A

Step-by-step explanation:

If you count how many 2f's there are, there are 6

B

Step-by-step explanation:

No. of times 2t is multiplied becomes the power of 2t

(2t)⁶

no he doesnt because "-16' is negatiive

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.
