Answer 2

Answer:

Hy buddy..

Step-by-step explanation:

1. 0.2 and 0.3

2/10;3/10.

(2×10)/(10×10). ; (3×10)/(10×10)

20/100 ; 30/100

Therefore,21/100,22/100 are the rational numbers between 0.2 and 0.3

2.{(2^0+5^0)7^0} = (1+1)/1 = 2/1 = 2 【a^0 = 1 if a not equal to 0】

3. 178x^12-5x+5466

4.(21√21) / 6√3

= 7×3 (√7×√3) / 2×3√3

= 7√7 / 2

5. 0 is the degree of constant polynomial.

6.cx+d = 0

cx=-d

x = -d / c
