Calculate both numbers:
1+3=4
When multiplying a number by 11, you add both digits together and place it in between the numbers:
13x11=143
Hi! I’m not positive, but I believe it would be D., 6 is the only one that is evenly divided by 3. Once again I’m not positive, I’m only a middle schooler so.... yeah.
Answer:
8
Step-by-step explanation:
It depends what mathematics you know
Perhaps the most basic way would be by approximation. You could start with, say, 5. 5*5*5= 125. Then 5 is to small to be the cube root of 512.
Try 10: 10*10*10=1000: Too bi. But now we know that the number we want is between 5 and 10.
Try 8: 8*8*8=512.
