Hello! And thank you for your question!
Use Pemdas to get
3^(n+2)*4=3^28
Rewrite the equation:
3^4(n+2) = 3^28
Cancel the base of 3:
4(n + 2) = 28
Then divide 4 on both sides:
2 + n = 28/4
Simplify 28/4:
2 + n = 7
Subtract 2 on both sides:
n = 7 - 2
Finally simplify 7 - 2:
n = 5
Final Answer:
n = 5
translate, call the number, n
Eight more than (8+) twice a number increased by 3 (2(n+3)) is equal to (=) 79 (79)
8+2(n+3)=79
minus 8 both sides
2(n+3)=71
divide both sides by 2
n+3=35.5
minus 3 both sides
n=32.5
the number is 32.5
