Factor x^10 +y^4 using the sum of squares
(hint: x^10 = (x^5)^2 and y^4 = (y^2)^2)

cannot be factorized that is cannot be represented as products of lower degree polynomials.

Solution:

Need to factor using the sum of squares that is we need to factorize

Using law of exponent

On applying this we get,

But there is no direct formula of which can provide factors.

Hence we can say that cannot be factorize that is cannot be represented as products of lower degree polynomials.

meaning of term low   inflation is when prices of commodities does not change very highly.so low inflation is   not a sign of healthy economy.the demand of goods becomes higher due to some faulty measures taken by government

there are two kind of inflation

1. positive inflation : when supply of goods is less than prices of those goods rise.

2. negative inflation : when supply of any good is very high so it,s price will fall.

so option c is true : struggling economy because it results from a steady rise in demand.
