Answer:
Step-by-step explanation:
7^8*7=
5764801 * 7= 40353607
A. 7^3*7^3= 343*343= 117649 <--- not the answer
B. 7^18/7^9= 40353607 <---- right answer
C. (7^3)^3= 343^3= 40353607 <------ right answer
D. 7^5+7^4= 16807+2401= 19208 <---- not the answer
E. 7^5*7^4= 16807*2401= 40353607 <---- right answer
For this case, we must find an expression equivalent to:

By definition of power properties we have:

Rewriting the previous expression we have:
The "-" are canceled and we take into account that:

So:

According to one of the properties of powers of the same base, we must put the same base and add the exponents:

Answer:

Option B
Answer:
2a) $180
2b) $1440
Step-by-step explanation:
2a) Basically Samuel works for 6 hours a day and earns 7.50 per hour, so you have to do 7.50 x 6 to see how much he earns per day (which in this case is $45). You then have to multiply $45 to 4 since he earns $45 per day and works 4 days per week (which is $180).
2b) After finding out how much he earns per week ($180 from the previous question), you then have to multiply $180 by 8 as $180 is the amount he earns per week and since he works for 8 weeks you have to multiply $180 by 8 (the answer is then $1440).
sorry if I'm not making sense, i tried :) good luck!
