Can 45/112 be simplified


45 and 112 are relatively prime so no, it can't be simplified further.

How to simplify ratios using scientific calculator fx-991ms


If you enter the ratios using the fraction entry key ( [a b/c] the results will be displayed as fractions. And when the calculator displays fractions they are always in their reduced form.
In general, when you are manipulating fractions ( Pi/2 is no a fraction even if you write it as one) you can try to simplify them by looking for the greatest common factor (GCF) of the numerator and denominator. When you simplify by the GCF the fraction that is left is in its reduced form.

(a + 2b)(a2 - 2ab - 4b2)


I believe that the algebraic expression should be written as:
(a + 2b)(a^2 - 2ab - 4b^2)

which can be rewritten as:
(a + 2b)^2 * (a - 2b)


The simplified form of this expression is:
(a^3 - 2a^2b - 4ab^2 + 2a^2b - 4ab^2 - 8b^3)

which can then be further simplified as:
(a^3 - 8b^3)

Simplify 4x^2-36/x^2+2x-15*2x^2+11x+5/16x^2+16x-96/6x^2-7x+2/3x^2-4x-4


-42x^2 - 36/x^2 + 18x + 47/48x^2 - 4

I am confident that this is the simplified form.

Can anyone help me to solve this problem? 11^23 mod 187


One way to do this is to simplify it piece by piece. We know 11^23 = 11 * 11 * 11 * 11^20, and we know
that 11 * 11 * 11 = 1331 in to find this modulo 187 we look at 1331/187 which is > 7, so we can take 1331 - 7 * 187
which is 22. So 11^3 mod 187 is 22. we can simplify 11 ^23 = ( 11^3 ) * 7 * 11^2 because we know 11^3 = 22
we can write this as 22 * 7 * 11^2. and 11^2 mod 187 is 121 so now have a number to modulo.
11*7*121 mod 187 = 9317 mod 187 this is 88. Hope this helps you understand simplifying.

2/(x+1)+3/(x+2)


(5x+7)/(x^2+3x+2)

is the simplified answer because you can't break up the polynomials. The polynomials are like groups and you can't break them apart unless the polynomial itself can be simplified like

2x+4

can be simplified to 2(x+2)

so in which case you could simplify the problem down further.
