Question

6²x6⁴-4³(3⁶-1)

Answer 1

\(6^2.6^4-4^3\left(3^6-1\right)\)

\(=6^6-\left(2^2\right)^3\left(3^6-1\right)\)

\(=\left(2.3\right)^6-2^6\left(3^6-1\right)\)

\(=2^6.3^6-2^6.3^6+2^6\)

\(=2^6\)

\(=64\)

Answer 2

\(6^2.6^4-4^3\left(3^6-1\right)\)

\(=6^{2+4}-\left(2^2\right)^3\left(3^6-1\right)\)

\(=6^6-\left(2^6.3^6-2^6\right)\)

\(=6^6-\left(6^6-2^6\right)=6^6-6^6+2^6=2^6=64\)
