Answer 2

Answer:

Required numeric value of 5( - 5 )^3 - 2( - 5 )^2 + 3( - 5 ) - 2 is - 767.

Step-by-step explanation:

We have to simplify 5( - 5 )^3 - 2( - 5 )^2 + 3( - 5 ) - 2, where ^ represent the power or index or exponent, and index or exponent or power on a number represents the number of times of the multiples of that number.

So, ( - 5 )^3 should be - 5 x - 5 x  - 5 , since it has 3 as power on it, - 5 x - 5 x - 5 = - 125.

( - 5 )^2 should be - 5 x - 5 = 25.

Thus,

= > 5( - 5 )^3 - 2( - 5 )^2 + 3( - 5 ) - 2

= > 5( - 125 ) - 2( 25 ) - 15 - 2

= > - 625 - 50 - 15 - 2

= > - 675 - 17

= >  - 692

Hence the required numeric value of 5( - 5 )^3 - 2( - 5 )^2 + 3( - 5 ) - 2 is - 767.
