a)2x8=16
b)4x8=32
If you understand the transitive properties of multiplication, then the answer to a) tells you that if you double the 2 (to 4) it is the same as doubling the solution (16) ----> b) could be thought of or read as doubling the 16 or reduced to 16+16 = 32
Alternatively you may notice a binary power series developing, that is, w/o solving for b) we see 21 22 23 24 ----> the solution to b) is 25=32
One other implication of the power series:
a) 21x23 = 24 =16 ------>
b)22x23 = 22+3 = 25 = 32

How can you use 2 times 8 to find 4 times 8?
You can use 2*8 to find 4*8 by solving 2*8, then multiplying it by 2. This is equivalent to 4*8, or 32.
How can you use 2 facts to find 4 times 9?
You can use the fact that 4 is equal to 2 times 2 and the fact that 9 can be expressed as 3 times 3. By multiplying these facts, you can calculate 4 times 9 as follows: 4 times 9 equals (2 times 2) times (3 times 3). This can be rearranged to (2 times 3) times (2 times 3), which simplifies to 6 times 6, giving you 36 as the answer.
How can you use 4 times 7 to find 8 times 7?
You can use 4x7 to find 8x7 because 4 x 2 is 8, and you are simply doubling one of the numbers you are multiplying, (4 to 8) and so multiply your answer from 4x7 by 2 to get the answer to 8x7. 4x7 is 28 and 8x7 is 56, and 28 x 2 is 56.
How can you use doubling to find the product of 4 times 7?
since 4 is 2 times 2 just double 7 twice: 7 doubled = 14 and then 14 double = 28
What is the perimeter of an object 3 in by 4 in?
To find the perimeter, find 2 times the length and add 2 times the width. 2(3) + 2(4) = ? 6 + 8 = 14 inches
How can you use 4s facts to find 7 times 8 give the product in your explanation?
4 times 7 = 28 2( 4 times 7 ) = 2 times 28 = 56. I hoped I helped. XOXO W T F you don't know :(
How do you find 22 and times 4. Which calculations should she use?
I know my 22 times table so it is 88.For those who did not advance beyond the 12 times tables at school, the easiest method probably is22 * 4 = (11 * 2) * 4 = 11 * (2 * 4) = 11 * 8 = 88 .
Find the answer to find 2 times as much as 2 less than 6?
2 x 4 = 8
How do you find the cube root of -8?
Don't know how you find it but I guess the answer is -2. -2 x -2 =4 4 X -2 = -8
How do you use 4 x 4 to find the product of 8 x 4?
double 4 times 4
What does 6! 2! 4! 3! equal?
To calculate (6! \times 2! \times 4! \times 3!), we first find the factorials: (6! = 720) (2! = 2) (4! = 24) (3! = 6) Now, multiplying these together: (720 \times 2 \times 24 \times 6 = 207360). Thus, (6! \times 2! \times 4! \times 3! = 207360).
What multiplicalion fact can you double to find 4times7?
To find 4 times 7, you can double the multiplication fact of 2 times 7. Since 2 times 7 equals 14, doubling that gives you 4 times 7, which also equals 28. Thus, 4 times 7 can be derived from doubling 2 times 7.
