Write the product of
7 x 7 x 7 x 7
in exponential form.

I believe it's 7^3 (to the power of 3)

Step-by-step explanation:

7⁴

Step-by-step explanation:

An exponent is the same as an index and tells us what a power is made up of.

7  ×  7  ×  7  ×  7 = 7⁴

The powers of 7 are: 7; 49; 343; 2,401.

They are written with exponents as:

7¹; 7²; 7³; 7⁴

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
