Question

I don't really understand exponents well I was wondering if I could get some help on this plz ​

Answer 1

Ok so do 9 times itself 5 times so basically its this:

9*9*9*9*9

Next do the same but 3 times:

9*9*9

Exponents are not this:

9*3

But this:

9*9*9

Your answer:

59049/729

Another way to say it:

59049 over 729

There is your answer hope this helps

Answer 2

Answer:

9^2 (9 to the power of 2)

Step-by-step explanation:

Ok, this is how you find exponents:

Well, exponents are really just abbreviated multiplication, so to find the numerical value of 9^5 and 9^3, you need to multiply 9 by itself 5 times and 3 times, then divide.

9*9*9*9*9= 59049

9*9*9= 729

Then you divide: 59049/729= 81.

But the question asks to rewrite the answer using a single positive exponent, so now we simplify 81 into an exponent.

The square root of 81= 9

9*9=81

81 as an exponent= 9^2 (or 9 multiplied 2 times)

Another simple trick for solving exponents is to subtract the exponents:

9^5-9^3= 9^2 (5-3=2)

I hope this answer was helpful!
