Answer 1

Answer:

5.73 X 105  > 3.45 x 106

17.253 X 100 > 3.217 x 106

5x - 2 = 13

3⁹

Step-by-step explanation:

.compare : - a) 5.73 X 105 & 3.45 x 106 b]3.217 x 106 & 17.253 X 100

5.73 X 105   = (3.45 + 2.28) * 105 = 3.45 * 105 + 2.28 * 105

& 3.45 x 106  = 3.45 * (105 + 1) = 3.45 * 105 + 3.45

2.28 * 105 > 3.45

=> 5.73 X 105  > 3.45 x 106  

3.217 x 106  = 3.217 * (100 + 6) = 3.217 * 100 +  3.217 * 6

17.253 X 100 =  (3.217 + 14.036 ) * 100 = 3.217 * 100  + 14.036 * 100

14.036 * 100 > 3.217 * 6

=>  17.253 X 100 > 3.217 x 106

5ˣ = 125

=> 5ˣ = 5³

=> x = 3

5x - 2 = 5 * 3 - 2 = 13

(27)³

= (3³)³

= 3⁹

Let say X should be multiply 15, so that the product may be ş

15X = s

=> X = s/15
