(a)
and 
Step-by-step explanation:
Required
Which of a to d has no solution
(a) and
We have:
Sole for m
Divide by 6
So, we have:
and
implies that: m = -6,-7,-8,-9.....
implies that m = -3,-2,-1,0.....
<em>Hence, there is no solution</em>
Answer:
A
Step-by-step explanation:
Add the number of decimal places of the two numbers being multiplied to know the number of decimal places of the product.
A: 3.48 x 42.37 = 147.4476
2 decimal places + 2 decimal places = 4 decimal places
Only choice A is correct.
Answer:

Step-by-step explanation:
Answer:
=1.23*10^6
Step-by-step explanation:
We have to calculate
(1.93*10^7 )-(9.7*10^6)
In order to add or subtract two numbers in scientific notation, we have to make sure that the power of exponents in both numbers is same.
We have to reduce the power of 10 in first number from 7 to 6
So,
Step 1:
1.93*10^7=1.93*10*10^6
=10.93*10^6
Now,
Step 2:
=(1.93*10^7 )-(9.7*10^6 )
= 10.93*10^6- 9.7*10^6
Step 3:
=(10.93-9.7)*10^6
=1.23*10^6
