OpenStudy (welshfella):
the base of the log is 81 so we can write 81^x = 3 find the value of x
OpenStudy (welshfella):
HInt: 3 is the 4th root of 81
OpenStudy (anonymous):
Okay would it be 4
OpenStudy (welshfella):
no its 1/4 because 81 ^ (1/4) = 3 exponent 1/2 = square root exponent 1/4 = 4th root etc
OpenStudy (welshfella):
for fractional exponents:- |dw:1437663761032:dw|
