Explicação passo a passo:

$\mathsf{a = 2^5.2^3 = 2^{5 + 3} = 2^8}$

$\mathsf{b = 4^8:4^5 = 4^{8 - 5} = 4^3 = (2^2)^3 = 2^{2 \times 3} = 2^6}$

$\mathsf{c = (6^2)^3 = ((2.3)^2)^3 = 2^6.3^6}$

$\mathsf{a + b - c = 2^8 + 2^6 + 2^6.3^6}$

$\mathsf{a + b - c = 2^6(2^2 + 1 + 3^6)}$

$\mathsf{a + b - c = 64(4 + 1 + 729)}$

$\mathsf{a + b - c = 64(734)}$

$\boxed{\boxed{\mathsf{a + b + c = 49.976}}}$
