Give one example of when you would use the friendly numbers strategy to subtract.

Answers

I would say: when we want to substract numbers that are close to each other, but when the respective digits of the number from which the second number is subtracted are lower than in the other number.

For example, when we want to substract 18 from 21. Those two numbers are very close, but if you did it digit by digit, your would run into a problem.

So instead you can collect their differences to the friendly number 20: 21 is one number away from 20, and 18 two numbers, which makes a total of 3 numbers: and 3 is the solution!

For this case, we use the strategy of friendly numbers when subtraction is something complex to do mentally.

Let's suppose that we have the following subtraction:

$117 - 83$

Using friendly numbers we have:

$(100 + 17) - (80 + 3)$

Then, applying the associative property we have:

$(100 - 80) + (17 - 3)$

Doing the calculations we have:

$20 + 14 = 34$

Finally we have:

$117 - 83 = 34$

Which terms give is the perfect square of 3x4? A. 6x8 B. 6x16 C. 9x8 D. 9x16

Answers

A perfect square is the product when a number is multiplied to itself. Hence,the square of (3x4) is (3 x 4 x 3 x 4). We can rearrange this and have (3 x 3) x (4 x 4) which gives you 9 x 16. Thus, we have the perfect square of (3x4) re-written as (9 x 16). Thus, the answer is D: 9 x 16.

Answer:

The correct option is C.

Step-by-step explanation:

The given term is 3x⁴.

We have to find the perfect square of 3x⁴.

$(3x^4)^2=3^2* (x^4)^2$ $[\because (ab)^x=a^xb^x]$

$(3x^4)^2=9* x^(4(2))$ $[\because (a^x)y=a^(xy)$

$(3x^4)^2=9* x^8$

$(3x^4)^2=9x^8$

The perfect square of given expression is $9x^8$ .

Therefore option C is correct.
