jika 2 pangkat a + 1 = 64 dan 3 pangkat b + 1 = 27, Berapakah nilai a ditambah b?

•2 pangkat a+1 = 64
2 pangkat 5+1=64
•3 pangkat b+1=27
3 pangkat 2+1=27
a+b=?
5+2=7.
semoga bermanfaat

2^(a+1) = 64
2^a × 2^1 = 2^6
2^a = 2^6 : 2^1
2^a = 2^5
a = 5
3^(b+1) = 27
3^b × 3^1 = 3^3
3^b = 3^3 : 3^1
3^b = 3^2
b = 2
a+b = 5+2
= 7
