If the bases are the same, then u keep the same base and add the exponents

examples :
2^3 * 2^4 = 2^(3 + 4) = 2^7
3^3 * 3^3 = 3^(3 + 3) = 3^6

this does not apply if u have different bases
if u have different bases, u have to work them out..
examples :
2^2 * 3^2 = 4 * 9 = 36
3^3 * 2^2 = 27 * 4 = 108

You add the exponents and multiply the coefficient, so 8²*8² would be 64 with 4 being the exponent

Gavin is starting a running plan to train for a race. In the first week of his running plan, Gavin will run 5 miles. The plan ca

<h2>Answer:</h2><h2>Gavin would be expected to run during 36.5 miles during his 11th week of the training plan</h2>

Step-by-step explanation:

In the first week of his running plan,the number of miles covered = 5 miles

Weekly mileage will increase by 3.5 miles every week.

At the end of second week, the number of miles covered = 5 + 3.5 = 8.5

At the end of third week, the number of miles covered = 8.5 + 3.5 = 12

The series is 5, 8.5, 12, ...

Consider this as an AP, where a = 5, d = 3.5

By formula,  

 a_{n}  = a + (n-1)d

Substituting the values in the above equation, we get

 a_{11} = 5 + (10-1) 3.5

= 5 +(9)3.5

= 5 + 31.5

=36.5 miles.

Gavin would be expected to run during 36.5 miles during his 11th week of the training plan
