Answer 1

Step-by-step explanation:

ince I'm multiplying, I can move things around and simplify some of this stuff easily:

(2.6 × 105) (9.2 × 10–13)

= (2.6) (105) (9.2) (10–13)

= (2.6) (9.2) (105) (10–13)

= (2.6) (9.2) (105–13)

= (2.6) (9.2) (10–8)

Okay; I've simplified the power-of-ten part. Now I have to deal with the 2.6 times 9.2, remembering to convert my product to scientific notation:

2.6 × 9.2 = 23.92 = 2.392 × 10 = 2.392 × 101

Putting it all together, I have:

(2.6 × 105) (9.2 × 10–13)

= (2.6) (9.2) (10–8)

= (2.392 × 101) (10–8)

= (2.392)(101) (10–8)

= (2.392) (101–8)

= 2.392 × 10–7

Then (2.6 × 105) (9.2 × 10–13) = 2.392 × 10–7

Answer 2

Answer:

axaxax .... taken 10 times, it is $a^{10}$

Step-by-step explanation:

axaxax .... taken 10 times

For 1 time, it is $a = a^1$

For 2 times, it is axa $=a^2$

For 3 times, it is axaxa $=a^3$

Therefore, for n times, it is $a^n$

Putting the value of n as 10:

For 10 times, it is $a^{10}$
