Question

\(P=\frac{2^{12}.3^5-4^6.3^6}{2^{12}.9^3+8^4.3^5}\)

Answer 1

\(\frac{2^{12}.3^5-4^6.3^6}{2^{12}.9^3+8^4.3^5}\)

\(=\frac{2^{12}.3^5-4^6.3.3^5}{2^{12}.3.3^5+4^6.3^5}\)

\(=\frac{1-3}{3+1}\)

\(=\frac{-1}{2}\)

Answer 2

P=2¹².3⁵-4⁶.3⁶/2¹².9³+8⁴.3⁵

P=2¹².3⁵-(2²)⁶.3⁶/2¹².(3³)³+(2³)⁴.3⁵

P=2¹².3⁵-2¹².3⁶/2¹².3⁹+2¹².3⁵

P=2¹².(3⁵-3⁶)/2¹².(3⁹+3⁵)

P=3⁵-3⁶/3⁹+3⁵
