Question

(3^2-2^3)^2×(8^5:4^7)^2 va rog frumos ​

Answer 1

Răspuns:

$( {3}^{2} - {2}^{3}) {}^{2} \times ( {8}^{5} \div {4}^{7} ) {}^{2} = \\ (9 - 8) {}^{2} \times [( {2}^{3} ) {}^{5} \div ( {2}^{2} ) {}^{7} ] {}^{2} = \\ {1}^{2} \times ( {2}^{15} \div {2}^{14} ) {}^{2} = \\ 1 \times ({2}^{1})^{2} = \\ 1 \times {2}^{2} = \\ 1 \times 4 = 4$

sper că te-am ajutat!

Answer 2

Răspuns:

Explicație pas cu pas:

( 3² - 2³)² x ( 8⁵ : 4⁷)² = 4

= ( 9 - 8 )² x ( 2⁽³ˣ⁵⁾ : 2⁽²ˣ⁷⁾ )² =

= 1² x ( 2¹⁵ : 2¹⁴)² =

= 1 x ( 2⁽¹⁵⁻¹⁴⁾ )² =

= 1 x (2¹)² =

= 1 x 2² =

= 1 x 4 =

= 4
