Question

Me pueden responder las actividades 1 2 y 3 con proceso y explicacion paso a paso

de la pagina 90 texto integrado 9no matematicas por favor se lo suplico

Answer 1

1) c, d, a, b

2. D

3. B

Explanation:

1. (-2/7)^4 / (-2/7)^2 = (-2/7)^4-2 = (-2/7)^2
2. (-2/7)^6 / (-2/7)^12 = (-2/7)^7-12 = (-2/7)^-6

3. {[(-2/7)^6]}^-4 = 6x0=0 and 0x-4=0

A number with exponent 0 = 1

4. (-2)^-1 = -7/2

2) 5square 7^x = 7^3
x/5 = 3

X = 5*3

X = 15

3) (50 square root)/(98square root/64square root)

50 = 2 * 5^2
98 = 2 * 7^2
64 = 8^2
[(5 * square root 2)/ 1] / (7 * square root 2)/8)

(40 square root 2) / (7 square root 2) = 40/7

Answer 2

9/18= 1/2 is the correct anwser so that would mean your anwser would be B
