Question

Help please Simplify the expression. Assume the variables represent any real numbers and use absolute value as necessary.
(81a^(8)b^(20)^(1/4))

Answer 1

81a^(8) b^(20)^(1/4)

81a^8 b^5 is all I can see to do to it

Answer 2

exponents with exponents multiply, for example:

a^3^4 means

(a^3).(a^3).(a^3).(a^3) means

(a.a.a).(a.a.a).(a.a.a).(a.a.a) means

a.a.a.a.a.a.a.a.a.a.a.a means

12 little a's; or, a^12

Answer 3

my choices are as follows: 1/3|a^2b^5| or|3a^2b^5| or 81/a^8b^20

Answer 4

then I got know idea what they want you to do ....

Answer 5

81 doesnt simplify to anything other than perhaps its perfect prime factors, but what good does that do since none of the cancel out?

Answer 6

are you sure you typed inthe whole problem? there isnt any secrets your leaving out is there? :)

Answer 7

(81a^(8)b^(20))^(1/4)) added one ) after the ^20

Answer 8

got it it is |3a^2b^5|

Answer 9

ahh.... that does help ;) good job
