Question

Sa se calculeze (2^5)^3:(2^2)^7×3^3+5^21×5^4:5^23-2^5

Answer 1

(2^5)^3:(2^2)^7×3^3+5^21×5^4:5^23-2^5 =

2^15 : 2^14 x 3^3 + 5^21 x 5^4 : 5^23 - 2^5 =

2^(15-14) x 27 + 5^(21+4-23) - 32 =

2 x 27 + 5^2 - 32 =

54 + 25 - 32 =

79 - 32 =

47

Answer 2

( 2'5 )' 3 : ( 2'2 )' 7 * 3'3 + 5'21 * 5'4 : 5'23 - 2'5=
=2'15 : 2'14 * 27 + 5'25 : 5'23 - 32=
=2'1 * 27 + 5'2 - 32=
= 2 * 27 + 25 - 32=
= 54 + 25 - 32=
= 79 - 32=
= 47.
