Answer 1

Răspuns:

Explicație pas cu pas:

2³ × 2⁵ × (2⁷)² : 2¹⁵ = 2³ × 2⁵ × 2¹⁴ : 2¹⁵

= 2³+⁵+¹⁴-¹⁵ = 2⁷ = 128

Answer 2

➣ Rezolvare:

$\bf{2^{3} \times {2}^{5} \times ( {2}^{7} )^{2} \div {2}^{15 } = }$

$\bf{ = {2}^{3} \times {2}^{5} \times {2}^{7 \times 2} \div {2}^{15} = }$

$\bf{ = {2}^{3} \times {2}^{5} \times {2}^{14} \div {2}^{15 } = }$

$\bf{ = {2}^{3 + 5} \times {2}^{14} \div {2}^{15} = }$

$\bf{ = {2}^{8} \times {2}^{14} \div {2}^{15} = }$

$\bf{ = 2^{8 + 14} \div {2}^{15} = }$

$\bf{ = {2}^{22} \div {2}^{15} = }$

$\bf{ = 2 ^{22 - 15} = \boxed{ {2}^{7} = 128 } }$
