(2sqrt6)^6=13824(26)6=13824

Explanation:

(2sqrt6)^6(26)6

= 2^6xx(sqrt6)^626×(6)6

= (2xx2xx2xx2xx2xx2)xx(sqrt(6xx6xx6xx6xx6xx6))(2×2×2×2×2×2)×(6×6×6×6×6×6)

= 64xxsqrt(ul(6xx6)xxul(6xx6)xxul(6xx6))64×6×6−−−×6×6−−−×6×6−−−

= 64xx6xx6xx6

= 64xx216

= 13824

13,824

Explanation:

Use the laws of indices.

(2 sqrt6)^6 = 2^6 xx (sqrt6)^6" "larr ((ab)^m = a^m b^m)

=2^6 xx (6)^(6/2)" "larr sqrtx = x^(1/2)

=2^6 xx 6^3

=(2xx2xx2xx2xx2xx2)xx (6xx6xx6)

It helps to know the powers less than 1000 by heart.

= 64 xx 216

=13,824
