Question

a) 4³-2•3³-(16⁰-9²)


b) 5⁴-25:(4⁶ • 3- 12263)​

Answer 1

$a) 4^{3} -2 .3^{3} -(16^{0} -9^{2} )$

$64 - 2 . 27 - (1-81)$

$64 - 54 - (-80)$

$64-54 + 80$

$10+80$

$90$

$b) 5^{4} -25:(4^{6} . 3- 12263)$

$625-25:(4096.3 - 12263)$

$625 - 25: (12288-12263)$

$625 - 25 : 25$

$625-1$

$624$
