can you solve this?

Question

9 times itself 9 times, then the result times itself 9 times

Answer 1

(9^9)^9 [ (9 to the ninth power) to the ninth power ]
= 9^81 [9 to the eighty-first power, or 9 times itself 81 times ]
you can calculate this as
= (9^27)^3 to get
= (58149737003040059690390169)^3

or calculate as
(9^9)^9 = (387420489)^9
= ((387420489)^3)^3
= (58149737003040059690390169)^3

= 1.96627050475552913618075
90852691 x 10^77

If you use a regular calculator, you should get
scientific notation. I was able to type in the numbers
above into the calculator on the computer and multiply,
without losing any digits to rounding. (When I plugged these equations into Excel as a formula, the numbers got so large they rounded up.)

Note:
Most of the other answers are too small, so I don't think those can be right. The one answer that looks large enough seems the same, but rounded down.

Two people vetoed my answer when I wasn't finished typing it. For the final answer, I checked it three ways and got the same result each time:

(58149737003040059690390169)
times (58149737003040059690390169)
times (58149737003040059690390169)

= 1.96627050475552913618075
90852691 x 10^77

387420489 times itself nine times
= 1.96627050475552913618075
90852691 x 10^77

And I took this final answer and divided by 9
81 times until it reduced to 1. So it is the same as
9 times itself 81 times. (If it had been rounded, I don't think
it would come out even working backwards.)

If the calculator on the computer rounds it differently from others, that explains why the answers are slightly different.

Answer 2

x² = x+6 x² - x - 6 = 0 (x - 3)(x + 2) = 0 So x = 3 or - 2 x² + 2x = 0 x(x + 2) = 0 So x = 0 or - 2 60 = x² - 4x x²- 4x - 60 = 0 (x - 10)(x + 6) = 0 So x = 10 or -6 4x = x² - 40 5 x² - 4x - 40 5 = 0 (x - 9)(x + 5) = 0 So x = 9 or -5 -6x = x² + 9 x² + 6x + 9 = 0 (x + 3)(x + 3) = 0 (x + 3)² = 0 So x = -3 -15=x² + 8x x² + 8x +15 = 0 (x + 5)(x + 3) = 0 So x = -5 or -3 -9x = x² + 14 x² + 9x + 14 = 0 (x + 7)(x + 2) = 0 So x = -7 or - 2 desire that facilitates. =D

Answer 3

(9^9)(9) = 3486784401
3486784401^9

Answer 4

9x9=81 then 81xs 9 and thats the answer=721

Answer 5

729

Answer 6

it would be (9^9)^9
it would be 387420489^9
which is 1.966270505*10^77
which is scientific notation

Answer 7

yes
