Answer:
(i) 8.5 × 10^-12
(ii) 9.42 × 10^-12
(iii) 602 × 10^15
(iv) 8.37 × 10^-9
(v) 3.186 × 10^10
Step-by-step explanation:
(i) 0.0000000000085
= 0.0000000000085 × 10^12/10^12
= 8.5/10^12
<u>= 8.5</u><u> </u><u>×</u><u> </u><u>10^-12</u>
(ii) 0.00000000000942
= 0.00000000000942 × 10^12/10^12
= 9.42/10^12
<u>= 9.42</u><u> </u><u>×</u><u> 10^-12</u>
(iii) 6020000000000000
<u>= 602 </u><u>×</u><u> </u><u>10^15</u>
(iv) 0.00000000837
= 0.00000000837 × 10^9/10^9
= 8.37/10^9
<u>= 8.37</u><u> </u><u>×</u><u> </u><u>10^-9</u>
(v) 31860000000
<u>= 3.186 </u><u>×</u><u> 10^10</u>

The solution of given problem 1.5 [ 3( 14.5 +7 ) -3 ] - 7.4 is 84.85
<em><u>Solution:</u></em>
Given problem is:
1.5 [ 3( 14.5 +7 ) -3 ] - 7.4
We have to use BODMAS rule to solve the problem
According to Bodmas rule, if an expression contains brackets ((), {}, []) we have to first solve or simplify the bracket followed by of (powers and roots etc.), then division, multiplication, addition and subtraction from left to right
Thus in the given problem, first we have to solve for brackets
Add 14.5 and 7 inside the brackets
![\rightarrow 1.5 [ 3( 14.5 +7 ) -3 ] - 7.4\\\\\rightarrow 1.5 [ 3(21.5) - 3 ] - 7.4](https://tex.z-dn.net/?f=%5Crightarrow%201.5%20%5B%203%28%2014.5%20%2B7%20%29%20-3%20%5D%20-%207.4%5C%5C%5C%5C%5Crightarrow%201.5%20%5B%203%2821.5%29%20-%203%20%5D%20-%207.4)
Multiply 3 with 21.5
![\rightarrow 1.5[64.5-3] - 7.4](https://tex.z-dn.net/?f=%5Crightarrow%201.5%5B64.5-3%5D%20-%207.4)
Now again solve for brackets by subtracting 3 from 64.5
Now perform multiplication of 1.5 and 61.5
Now perform subtraction
Thus the solution of given problem is 84.85
Answer:
me either. I think u have to solve it using the ordered pairs.
Step-by-step explanation:
6(w+5) represents the product of 6 and the sum of w and 5. the product means multiplication, and the sum means addition.
6(w+5) also equals 6w+6(5), or 6w+30, because of the distribution property.
