Answer 1

Explicação passo-a-passo:

(8:2).4+(3²-2²).2⁴-5

4.4+(3²-2²).2⁴-5

4.4+(9-2²).2⁴-5

4.4+(9-4).2⁴-5

4.4+5.2⁴-5

4.4+5.16-5

16+5.16-5

16+80-5

96-5

91

13+(10-8)+(7-4)+✓81-2⁵

13+2+(7-4)+✓81-2⁵

13+2+3+✓81-2⁵

13+2+3+9-2⁵

13+2+3+9-32

15+3+9-32

-5

Answer 2

Resposta:

$\left(8\div \:2\right)\cdot \:4+\left(3^2-2^2\right)\cdot \:2^4-5\\\\4\cdot \:4+\left(3^2-2^2\right)\cdot \:2^4-5\\\\4\cdot \:4+5\cdot \:2^4-5\\\\4\cdot \:4+5\cdot \:16-5\\\\16+5\cdot \:16-5\\\\16+80-5\\\\91$

__________________________________________________________

$13+\left(10-8\right)+\left(7-4\right)+\sqrt{81}-2^5\\\\13+10-8+7-4+\sqrt{81}-2^5\\\\13+10-8+7-4+9-2^5\\\\13+10-8+7-4+9=27\\\\27-2^5\\\\27-32\\\\-5$
