Step-by-step explanation:
we know that
Work =f*d
=25*100
=2500Joule
therefore work done is 2500Joule
I think it is 32, bc the value of x is 20 so your problem would look like this; 2 ( (20) - 4 )
For a sum of a number t and 23
t plus 23
LAW 2: The second law of indices tells us that when dividing a number with an exponent by the same number with an exponent, we have to subtract the powers. In algebraic form, this rule is as follows . The a represents the number that is divided by itself and m and n represent the powers.
