Answer:
Step-by-step explanation:
apply the indices law
- multiple means addition
- division means subtraction
- you are suppose to add the powers or subtract where necessary
- 4^9x 4^3= 4^5
- 6^5x6^2=6^7
- 8^6÷8=8^5
- 7^8÷7^6=7^2
5x - 2x = 63 + 57
3x = 120
x = 40
The answer is 36.
Because 20% of 36 is equal to 7.2
And 36 - 7.2 = 28.80
