Answer:
35/8
Step-by-step explanation:
1 3/4 = 1 + 3/4 = 4/4 + 3/4 = 7/4.
So 1 3/4 ÷ 2/5 = 7/4 × 5/2 = 35/8.
Equation: 21+n=43.23
Process to find n
21+n=43.23
Subtract 21 from both sides
n=22.23
Answer:
The solution of
is 64.
Step-by-step explanation:
In Mathematics when two negative numbers are multiplied the result is a positive number, i.e.
.
The expression to be solved is: ![(-8)^{2}](https://tex.z-dn.net/?f=%28-8%29%5E%7B2%7D)
Solve the above expression as follows:
![(-8)^{2}=(-8)\times (-8)=64](https://tex.z-dn.net/?f=%28-8%29%5E%7B2%7D%3D%28-8%29%5Ctimes%20%28-8%29%3D64)
Thus, the solution of
is 64.
