Scientific notation says, "leave only one guy to the left of the decimal point", so... 25.8 needs to turn to 2.58 then... multiplied by some power of 10, we just need to move the dot over one spot, so 10 at the 1 power,  \bf 2.58\times 10^1\implies 2.58\times 10

Answer ---> 2.58*10^1

So, when you write 10^n, you have to move the comma n times.

So you move the comma 1 time from 2.58 (moved the comma 1 time on the left) to the right and get 25.8

The larger of two numbers is 4 more than the smaller the sum of the two numbers is 74
lisabon 2012 [21]

Answer:

y = 35    x = 39

Step-by-step explanation:

Let large no = x and small no = y

According to the question,

x = 4 + y ------ (1)

x + y = 74 -------- (2)

Substituting (1) in (2)

( 4 + y ) + y = 74

4 + 2y= 74

2y = 74 -4

y = 70 / 2 = <u>35</u>

x = 4 + y

  = 4 + ( 35 )

   = <u> 39</u>
