Answer 1

Answer:

3) given =>

2x^2 + x -a =5

when x =0 then,

2* (0)^2 +0 -a = 5

0 + 0- a = 5

-a = 5

a= 5 . answer.

4) 3^5 * 10^5 * 25/ 5^7 *6^5

=> 3^5 * (2*5)^5 * 5^2 / 5^7 * (2*3)^5

=> 3^5 * 2^5 * 5^5 * 5^2 / 5^5* 5^2 * 2^5 * 3^5

=> 0. answer.

I hope it will help you. sorry I don't know About 5). you can delete this answer but the upper two answers are correct. I don't know about the last question.
