Answer:
A. 2^11
Step-by-step explanation:
(They are basically asking what's 2^4 × 2^7, but with more words.)
I usually do each exponent individually:
2^4 is the same as 2 × 2 × 2 × 2 = 16 (or you could have read the text to figure that out)
2^7 is the same as 2 × 2 × 2 × 2 × 2 × 2 × 2 = 128
Then just multiply 128 and 16 to get 2,048, and see which option also gives you 2,048.
BUT, you can also:
(Combine the exponents together to get your answer. Just remember that if it's multiplication you add them, and if it's division you subtract them.)
2^4 × 2^7
4 + 7 = 11
2^11 (This equals 2,048 btw. You don't even have to check all the options to get the answer).
Hope this helps friend :)
The last part I learned from another user, while answering one of your other questions. I personally find this mind blowing, lol.
Answer:
It was a 16.7% discount

You have to get the discount and divide it by the original price and it would be 0.16753 and so the percent becomes 16.7%
Answer:
1/2
Step-by-step explanation:
We first find the least common multiple, which is 6. Therefore, we can multiply 1/3 x 2/2 (since 2/2 is equal to one and won't change the final amount) and get 2/6. 2/6+1/6=3/6, or 1/2.
Answer:
5 / 9
Step-by-step explanation:
Total people = 24 + 30 = 54
Children = 30
30 / 54 = 5 / 9
Step-by-step explanation:
Any known 0 number with exponent 0 is known as undefined
If 2^x = 16, then the value of x is 4
Writing separated multiplication of numbers in short form is called product of powers property
If base is negative and exponent is odd the expression has negative value
