Question

(16^4×8^5:4^15+2^0+2^2)×4-5^2

Answer 1

(2^16 • 2^15 : 2^30 + 1 + 4) • 4 - 25 =
(2^31 : 2^30 + 5) • 4 - 25 =
28-25=
3

Answer 2

( 16⁴ x 8⁵ : 4¹⁵ + 2⁰ + 2² ) x 4 - 5² = 3

= [ ( 2⁴ )⁴ x ( 2³ ) ⁵ : ( 2² )¹⁵ + 1 + 4 ] x 4 - 25 =

=  ( 2¹⁶ x 2¹⁵ : 2³⁰ + 5 ) x 4 - 25 =

= ( 2 ⁽ ³¹ ⁻ ³⁰ ⁾  + 5 ) x 4 - 25 =

= ( 2¹ + 5 ) x 4 - 25 =

= 7 x 4 - 25 =

= 28 - 25 =

= 3
