What's 2 + 2 x 10?

!0 x 1,00 = ?

1,000 x 1,00,00=?

2 + 2 x 10 = 22

10 x 100 (?) = 1,000

1,000 x 10,000 (?) = 10,000,000

Step-by-step explanation:

For A, (2 + 2 x 10), you need to multiply first, 2 x 10 = 20. Then, you must add 2, which equals 22.

For B, which is (10 x 100, I think) you will multiply the top number by the bottom number, let’s say 100 is on the top. You will line thin up, 100 x 10. You will need to multiply 0 times 100, which is 000. You will then need to move over a slot, and then times 100 by 1. After doing that then you add your numbers, which gives you 1,000.

For C you do the same steps you used for B.

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
