can you solve this chemistry math problem showing all the steps?

Question

(6.7x10^-5)(1.2x10^10)^2
-----------------------------------
(8.1x10^-3)^11(2.5x10^2)
the anwser is 3.9x10^36 but i cant arrive at the anwser because i dont get what to do with the exponents on the outside of the brakets. thanks

Answer 1

Simplify the expression.
[(6.7*10^-5)(1.2*10^10)^2] / [(8.1*10^-3)^11(2.5*10^2)]

= {(6.7*1.2²) / [(8.1^11)(2.5)} {10^[-5 + 10*2 - (-3*11) - 2]}
= {(6.7*1.2²) / [(8.1^11)(2.5)} {10^[-5 + 20 + 33 - 2]}
= {3.9*10^(-10)} {10^46}
= 3.9 * 10^(-10 + 46)
= 3.9 * 10^36

Answer 2

(6.7x10^-5)(1.44x10^20)
----------------------------------
(9800000000x10^-33)(2.5x10^2)

9.6x10^15
---------------
(9.8x10^-24)(2.5x10^2)

9.6x10^15
---------------
24.5x10^-22

9.6/24.5 x 10^37

0.39 x 10^37

3.9 x 10^36

Hope this helps! :)
