Help me .. About indices

How this equation

2^p+2 - 3^q+1 = 5
changes into
4.2p - 3.3q = 5
?!
Please help

Hint: a^p+2 = a^p * a²

How 2^(p+2) - 3(q+1) =5 turns into 4.2p-3.3q=5 ?! \(\displaystyle \ \ \ \ \ \ \) And, the p and the q are exponents.

Can someone explain this .. T

Abinaya,

1) when Subhotosh Khan edited your line, he left out a "^" for exponentiation.

2^(p+2) - 3^(q+1) = 5 \(\displaystyle \ \ \ \ \ \ \) <------ This would be the correction.


2) The book and you should not be using decimal points for multiplication.
Use an asterisk or a pair of parentheses instead.


Your goal is to convert the first equation into

4*2^p - 3*3^q = 5
