The partial products of 28 x 14 are 112 and 280. 28 = 8 + 20 ⇒ 28 x 14 = 8 x 14 + 20 x 14 = 112 + 280 14 = 4 + 10 ⇒ 28 x 14 = 28 x 4 + 28 x 10 = 112 + 280 The partial products are the same in the different splits as 28 = 2 x 14. If the numbers had been, say, 17 x 28 then: 28 = 8 + 20 ⇒ 28 x 17 = 8 x 17 + 20 x 17 = 136 + 340 17 = 7 + 10 ⇒ 28 x 17 = 28 x 7 + 28 x 10 = 196 + 280
4 x 10^6 x 6 x 10^8 = 24 x 10^14 = 2.4 x 10^15 = 2,400,000,000,000,000
A million times a million is a trillion, so 200 trillion. or 200 x 10^12 = 2 x 10^14. You could also do it as 2 x 10^2 x 10^6 x 10^6, add the exponents of ten = 14.
-4-x = 10 -x = 10+4 -x = 14 x = -14
-4-x = 10 -x = 10+4 -x = 14 x = -14
-10 x - 7 - 14 = +70 - 14 = +56
Two methods are: .10 x 14 = 1.4 10 / 100 x 14 = 1.4
10 x 14 = 140
14 x 10 = 140
14 x 10 = 140
3x+10=14+2x so subtract 2x from both sides x+10=14 so x=14-10 so x = 4
14
170 x 140 = 17 x 10 x 14 x 10 = 17 x 14 x 100 = 23800

SQRT 14 x sqrt 10 is same as sqrt (14 x 10) = sqrt 140 sqrt 140 = 11.83
