Answer: 4^9
Step-by-step explanation:
4^-7 is just 1/4^7 so this is equal to 4^2 divided by 1/4^7. Dividing by a fraction is the same thing as multiplying by its reciprocal (just flip the fraction). So this whole equation is equal to 4^2 multiplied by 4^7. And when you multiply two exponents with the same base, the exponents are just added. So, your answer should be 4^9. Hope this helps! :)
Answer: No solution
Step-by-step explanation:
1. Expand the brackets- 9-3x+5x=2x+4
2. Add common terms- 9+2x=2x+4
3. Subtract 2x from both sides- 9=4
4. Nine cannot equal four and therefore, there is no solution.
