The answer would be 101
Steps:
2+8=10
10x10=100 (because of the exponent)
100+1=101
The answer is 3(5x+2) i hope this helps you.
Product means the result you get after multiplying. So you have to multiply the two numbers. 379*8 = 3032
11/21 written as a decimal would be 0.52381 and in percent, it would be 52.381%.
To solve percent, since the total or 1/1 is 100%, we have to remember that the answer is less than 100%. So, we move 2 decimal places right to make it into percent. Then, the answer is 52.381.
To solve percent, you would do 100/21. Then, you would get 4.7619047619. You multiply that by 11 and get 52.381. But, you have to move 2 places left since fractions are tens, hundreds. So, you would get 0.52381.
