First parenthesis, so youre looking at 2*5^2. Thats the same as 2*5*5, which is 50. You now have -2*50^2 Then you do exponants, which gives you 2500 (50^2), then multiply by -2, which is -5000.

Whenever u come to the question involving power, u have to solve it first before doing any computation.
-2(2*5^2)^2
Here 2 rules of indices which u have to know:
i)(a*b^m)^n=a^n*b^mn
ii)(a^m)^n=a^m*n
=-2(2^2*5^4)
=-2(4*625)
=-2*2500
=-5000

-2(2*5^2)^2
= -2(2*25)^2
= -2(50)^2
= -2(2500)
= -5000

-2(2*5^2)^2
-2(2*25)^2
-2(50)^2
(-100)^2
10000
* You would only need to distribute the -2 into the parenthesis if it was either (2+5^2) or (2-5^2), which is not the case.

= - 2(2 * 5^2)^2
= - 2(2 * 25)^2
= - 2(50)^2
= - 2(2,500)
= - 5,000

The answer will be a negative number. Do the calculations in parentheses first and the ^ calculations before the multiplication.
