i need to write each expression as a product of the same factor:
* = multiply can you check these please
a^2 i got a*a
19^3 i got 19*19*19
-6^2 i got 6*6*-1
-x^3 i got x*x*x*-1
(-5)^4 i got (-5)*(-5)*(-5)*(-5)*(-5)
4^3 i got 4*4*4
-(10)^2 im not sure how to do??
20^1 i got just : 20
.
Good job on most of the expressions! Let's go through them one by one:
1. a^2: You correctly wrote it as a*a. This means that you are multiplying "a" by itself.
2. 19^3: You correctly wrote it as 19*19*19. This means that you are multiplying 19 by itself three times.
3. -6^2: Here, you made a small mistake. The square operation takes precedence over negation, so you need to calculate the square of 6 first and then apply the negation sign. The correct expression is (-6)*(-6), or (-6)^2.
4. -x^3: You correctly wrote it as x*x*x*-1. This means that you are multiplying "x" by itself three times and then applying the negation (-1).
5. (-5)^4: You correctly wrote it as (-5)*(-5)*(-5)*(-5)*(-5). This means that you are multiplying -5 by itself four times.
6. 4^3: You correctly wrote it as 4*4*4. This means that you are multiplying 4 by itself three times.
7. -(10)^2: To correctly calculate this expression, you first need to calculate the square of 10, which is 10*10. Then, you apply the negation (-1) to the result. The correct expression is (-1)*(10)*(10), or -1*(10^2).
8. 20^1: You are right! Since any number raised to the power of 1 is the number itself, the expression 20^1 simplifies to just 20.
Great job overall! Remember to carefully follow the order of operations when working with expressions involving exponents and negations.
-(10)^2 = -(10*10) = -100
Otherwise, you are correct, as far as you went.
