how to convert indices into lograthims and vice versa
a² = 10
a is base
2 is power or exponent
loga10 = 2
Practice Problems
2logx+3log y = log aFind value of 'a'
2logx - log y = 1
a log x - blog y = 2 log 3
Laws of exponent (basic)
a^m + a^ n = (a)^m+n
2³+2⁴= 2³+⁴=2⁷
a^m÷a^n=a^m-n
2⁶÷2⁴=2⁶-⁴= 2²
(2³)⁵= (2)³*⁵= (2)¹⁵
a°= 1
(a)^-3= 1/ a^3
