Answer: ₹128
Step-by-step explanation:
To work out the simple interest, you need to work out 8% of ₹20,000 for 2 years, which is 1.08 * ₹20,000 = ₹21,600 in the first year and ₹23,200 in the second year
To work out the compound interest, you need to work out 8% of the new value
1st year: ₹21,600
2nd year: 8% of ₹21,600 = ₹23,328
The difference is ₹23,328 - ₹23,200 = ₹128
Answer:
its B
Step-by-step explanation:
3^4 can be written as:
3 to the power of 4.
3 is the base number, and 4 is the exponent.
An exponent is basically a summarized version of saying the base number multiplies against itself however many times, the exponent clarifies that.
So... we'd write it out as:
3^4 = 3 * 3 * 3 * 3
In the end we get:
3 * 3 = 9, 9 * 3 = 27, 27 * 3 = 81
3^4 = 81 | There's your conclusion.
I hope this helps, have a great rest of your day! ^ ^

First you have to canceled out the fours from both side 4x/4-12/4 so x=3 then you do the same thing to the 7x-18
4x-12.
4x/4-12/4. So x=3
The fours cancelled out
7x-18
7x/7-18/7. So x= 2 4/7
The sevens cancelled out
