Hi. Can we solve polynomial equations having decimals in power of X suchas 3X^2.5+X=76,, 5 X^4.5+9X^3.2=12 using this calculator? If yes then i will purchase this model..

[@prince3500]

Yes we can, but i recommend you to buy 991ex coz it has many useful features

1, then press M+

[@SzymekCSC]

@@noyonmoni4957 M means there's a non-zero value in memory (M variable). To remove the M indicator press keys in the following sequence: AC MODE 1 (COMP) 0 SHIFT RCL (STO) M+ (M). This stores a zero value in M variable, causing the M indicator to disappear.

For cubic equation? We need three answers? Then which process in casio can anyone pls reply

[@prince3500]

For cubic equations there is mode available

But for some equations of cubic it shows decimal and square roots then? Which process

@@user-ik8ys7ve5q calculator always gives correct value. If you are looking for single digit values, just remember that every numbers can be expanded to give equations and that includes whole numbers, fractions or decimals
