Question

resolver las potencias

​

Answer 1

Explicación paso a paso:

8^0=1 - (16/9)

1- 16/9= (9-16)/9

7/9

.

4^4= 256 + (1/2)^5

256+ 1/32= (8192 + 1)/32

8193/32

.

5x^2+4×-300=0

a=5, b=4, c=-300

aplica formula general de (-b +- raíz de b^2 -4ac)/2a

×= -4+-raiz (4^2-4(5.-300)/2(5)

(-4+-raiz de (16-6000))= 10

(-4 +- raiz de 6016)10

(-4+- 8raiz94)10

simplificas te queda

(-2 + 4raiz94)/5 =7,35629

(-2 - 4raiz94)/5= -8,15629
