Answer 1

Resposta:

Explicação passo a passo:

1-A)

$2^5-3^2*7^0=\\=32-9\cdot \:7^0\\=32-9\cdot \:1\\=32-9\\=23$

B)

$2^0+2^1+3^0+3^0-3^2=\\=1+2+3^0+3^0-3^2\\=1+2+1+3^0-3^2\\=1+2+1+1-3^2\\=1+2+1+1-9\\=-4$

C)

$10^0+10^{10} +10^0-10^1=\\=1+10000000000+10^0-10^1\\=1+10000000000+1-10^1\\=1+10000000000+1-10\\=9999999992$

D)

$45\div 5+21-1^5\cdot 2^2=\\\frac{45}{5}+21\left(-1\right)^5\cdot \:2^2=\\=9+21\left(-1\right)^5\cdot \:2^2\\=9+21\left(-1\right)\cdot \:2^2\\=9+21\left(-1\right)\cdot \:4\\=9-84\\=-75$

E)

$18-2\cdot \:3^2+3^4=\\=18-2\cdot \:9+3^4\\=18-2\cdot \:9+81\\=18-18+81\\=81$

2-

A)

$13^2=\\13*13=169$

B)

$7^3=\\7*7*7=\\=343$

C)

$3^5=\\3*3*3*3*3=\\=243$

D)

$25^2=\\25*25=\\=625$
